High-pressure emulsification relies on intense hydrodynamic stresses to break down droplets into the micrometer range. This model predicts the final droplet size based on the pressure drop and fluid properties, ensuring the system operates within the necessary turbulent and inertial regimes. Maintaining operation within these regimes is critical for achieving predictable and stable emulsions in dairy, pharmaceutical, and cosmetic applications.
