Abstract
This article summarizes the technical development and validation of a multiphase computational fluid dynamics (CFD) numerical method using a combined volume-of-fluid (VOF)/Lagrangian tracking model to analyze general dispersed multiphase-flow problems with free surfaces. The gas-liquid interfacial mass, momentum, and energy transfer are modeled by continuum surface mechanisms. A high-order TVD scheme is also implemented for capturing sharp interfaces between immiscible phases. The objectives of the present study are to develop and verify the fractional volume-of-fluid cell partitioning approach into a predictor-corrector algorithm, which is suitable for solving fluid flows at all speeds regimes, and to demonstrate the effectiveness of the present approach by simulating benchmark problems including coaxial jet atomization.
