Apparatus, methods, and systems for mixing and dispersing a dispersed phase in a medium

Apparatus and methods for mixing and dispersing a dispersed phase in a medium comprise a rotating surface for receiving the medium and an atomizing apparatus positioned at the rotating surface for depositing aerosolized constituents of the dispersed phase into the medium. The medium is made receptive and the dispersed phase is aerosolized. Constituents of the aerosolized dispersed phase are deposited into the receptive medium to form a compound or composite. The medium may be deposited onto a rotating disk, and the dispersed phase may be sprayed onto the disk. A thin film can be generated on the disk to transfer, distribute, and disperse the dispersed phase. Liquid ligaments formed at the edge of the rotating disk further transfer, distribute, and disperse the dispersed phase into the medium. Ligaments may be broken into aerosols or deformed by attenuation/drawing to further promote transfer, distribution, and dispersion. A bulk composite/compound may be collected.
