DISCLOSURE OF INVENTION

(19) According to FIG. 1A-1F, an apparatus for creating a swirling flow of fluid on a horizontal plane of the present invention comprises of transmission base 1 for creating swirling flow. The base is a circular base having a cone shape with a very low incline angle (shown in FIG. 1C). The suitable incline angle is about 10-15. The cone surface is sloped to a central apex where the swirling flow creating surface 2 is located symmetrically. In between swirling flow creating surfaces 2, there is at least one penetrable slit 3 along the edge of the swirling flow creating surface 2 for transmitting fluid from underpart of transmission base 1 through the penetrable slit 3 (shown in FIG. 1B) to an upper part of transmission base 1 to create swirling flow on the horizontal plane.

(20) Swirling flow creating surface 2 is curved outward to the circumferential wall of the cone (shown in FIG. 1D, section A) of which a beginning section of swirling flow creating surface 2 has to be the surface with a smallest angle of deviation of an emerging axis (a) of the penetrable slit 3. It is also the surface that is nearest to emerging axis (a) when compared with other surfaces around the emerging axis (a).

(21) Fluid with a certain pressure is forced to penetrate through the penetrable slit 3 to the upper part of transmission base 1 to be deflected and induce the fluid on transmission base 1 to flow along the swirling flow creating surface 2, which is the area that is difficult to flow through and induce fluid to flow attaching to swirling flow creating surface 2 by swirling flow creating surface 2.

(22) Swirling flow creating surface 2 is a set of surfaces that is designed to flow around a center of the transmission base 1 which is the plane of cone shape with a minimal slope and a minimal incline angle that is close to the horizontal plane.

(23) The flow of fluid from said profile will create the deflection and induce the fluid upon the transmission base 1 to flow attaching to the swirling flow creating surface 2 which is located around the transmission base 1 (shown in FIGS. 1A and 1D on arrow (b)), which has a minimal slope to the central apex, thus creating swirling flow of fluid on the plane in the manner of fluid sheet in laminar swirling flow with high velocity without turbulent flow and it is swirling on vertical to the horizontal plane (shown in 1F).

(24) According to FIGS. 2A-2F, an apparatus for creating a swirling flow of fluid on a horizontal plane of the present invention comprises a transmission base 1 to create swirling flow. The base is round and flat with a certain thickness (shown in FIG. 2C). The apparatus has a swirling flow creating surface 2 made as a wall cone sloped to the center with a minimal incline angle. The suitable incline angle is about 10-15 at which point the cone wall to be cut down and rearranged horizontally around center of transmission base 1 to reduce the height of transmission base to configure the transmission base being close to the horizontal plane. The said swirling creation surface 2 is located symmetrically around a center of the transmission base 1. In between swirling creation surfaces 2, there is at least one penetrable slit 3 along the edge of swirling flow creating surface 2 for transmitting fluid from the underpart of the transmission base 1 through the penetrable slit 3 (shown in FIG. 2B) to the upper part of transmission base 1 to create the swirling flow on the horizontal plane.

(25) Swirling flow creating surface 2 is curved outward to the circumferential wall of cone (shown in FIG. 2D, section A) of which a beginning section of the swirling flow creating surface 2 has to be the surface with a smallest angle of deviation of the emerging axis of the penetrable slit 3. It is also the surface that is nearest to the emerging axis (a) when compared with other surface around the emerging axis (a). Fluid with a certain pressure is forced to penetrate through the penetrable slit 3, to the upper part of transmission base 1 to be deflect and to induce fluid on transmission base 1 to flow along the swirling flow creating surface 2, which is the area that is difficult to flow through, and induce fluid to flow attaching to swirling flow creating surface 2 by swirling flow creating surface 2.

(26) Swirling flow creating surface 2 is set of surfaces that is designed to surround a center of transmission base 1 and that induce fluid to flow along the plane of transmission base 1 which is in round and flat shape. The flow of fluid from said profile is creating the deflection and inducing of fluid upon transmission base 1 to flow attaching to swirling flow creating surface 2 that is located surround transmission base 1 (shown in FIGS. 2A and 2D on arrow (b)), which has minimal slope to central apex The flow creates a swirling flow of fluid on a plane in the manner of fluid sheet in laminar swirling flow with high velocity without turbulent flow and it is swirling on vertical to the horizontal plane (shown in 2F).

(27) According to FIG. 3A-3F, an apparatus for creating a swirling flow of fluid on a horizontal plane of the present invention comprises a transmission base 1 to create swirling flow of fluid on the horizontal plane. The base is round and flat with a certain thickness (shown in FIG. 3E). Swirling flow creating surfaces 2 (shown in FIG. 3C) are located symmetrically around a center of the transmission base 1. In between swirling flow creating surfaces 2, there is at least one penetrable slit 3, along the edge of swirling flow creating surface 2 for transmitting fluid from underpart of transmission base 1 through the penetrable slit 3 (shown in FIG. 3D) to the upper part of the transmission base 1 to create the swirling flow on the horizontal plane.

(28) The swirling flow creating surface 2 (shown in FIG. 3C) is twisted as a concentric spiral to the center of transmission base 1. The beginning section of the edge of concentric spiral has to be the surface with a smallest angle of deviation of the emerging axis (a) of penetrable slit 3. It is also the surface that is nearest to emerging axis when compared with other surface surround emerging axis (a).

(29) Fluid with a certain pressure is forced to penetrate through the penetrable slit 3 (shown in FIG. 3D), to the upper part of transmission base 1, wherein the fluid flow is deflected and induces fluid on transmission base 1 to flow along the swirling flow creating surface 2, which is the area that is difficult to flow through and induce fluid to flow attaching to swirling flow creating surface 2 by swirling fluid flow 2.

(30) Swirling flow creating surface 2 is a set of surfaces that are designed to surround a center of transmission base 1 for inducing swirling flow of fluid on the horizontal plane of transmission base which is in round flat shape.

(31) The flow of fluid from said profile is creating the deflection and inducing of fluid upon transmission base 1 to flow attaching to the swirling flow creating surface 2 that is located around on transmission base 1 (shown in FIGS. 3A and 3C on arrow (b)). This process creates swirling flow of fluid on horizontal plane in the manner of fluid sheet in laminar swirling flow with high velocity without turbulent flow and it is swirling on vertical to the horizontal plane (shown in 3F).

(32) From the characteristic of apparatus for creating a swirling flow of fluid on the horizontal plane of the present invention, the swirling flow creating surface is has a curvature of which the beginning section has to be the surface with a smallest angel of deviation of the emerging axis of the penetrable slit. The said curved surface is nearest to the penetrable slit when compared with other surface surround the emerging axis, for deflecting the fluid which forced by a certain pressure to flow through the penetrable slit upon the transmission base to flow attaching to the swirling flow creating surface and induce the fluid on transmission base to flow attaching to swirling flow creating surface which is the area that is difficult to flow through. All the said 3 types of swirling flow creating surfaces are designed to surround the center of transmission base for creating the swirling flow of fluid on the horizontal plane of transmission base.

(33) The composition layout of the transmission base, the swirling flow creating surface, and the penetrable slit, in the said profile above are fixed according to the principle of Coanda profile. With such Coanda profile, the apparatus will deflect and induce fluid to flow attaching to the swirling flow creating surface which is the area that is hard to flow though. This phenomenon is called Coanda effect. Together with the profile located on the horizontal plane, it will create the swirling flow of fluid as fluid sheet with laminar swirling flow with high velocity without turbulent flow. It also has a clear distribution of centrifugal acceleration gradient on the horizontal plane of transmission base.

(34) In case install the apparatus for creating swirling flow of fluid of the present invention on the horizontal plane, the sum of gravity force act to the mass of fluid is perpendicular to swirling flow creating surface which will promote fluid to flow attaching swirling flow creating surface, making thick boundary layers, thereby the efficiency of apparatus, especially in the case of high density and high viscosity fluid.
