An introductory 2-Day course covering gas-particle and gas-liquid flows
Multiphase flows are encountered in a wide variety of industries including nuclear, aerospace, chemical, mechanical and biological engineering. Multiphase flows may involve gas-solid mixtures, gas-liquid mixtures and liquid-liquid mixtures. Based on the nature of the flow, a variety of computational techniques have been developed. These include Eulerian-Lagrangian methods for dilute dispersed flows including two-way coupling, Eulerian-Eulerian techniques with interface capturing and Eulerian-Eulerian methods for volume-averaged equations. The techniques for interface capturing include Volume of Fluid (VOF), Level-Sets (LS), and Front Tracking (FT).
This course will introduce the various techniques for multiphase flows by experts who have directly developed and implemented such techniques. Our intent is to give as many details as possible, and describe their implementation in a model Navier-Stokes solver for two-dimensional flows. The course is divided into two days, beginning with the governing equations and volume averaging of the phasic equations of a mixture. The modeling of the interphase coupling terms is discussed with their assessment in some complex flows. Day 1 will also cover the computation of dilute gas particle flows. Day 2 will cover the front tracking algorithm for gas liquid flows and other interface tracking algorithms including VOF, LS and coupled VOF and LS algorithms, followed by brief introduction to Eulerian-Eulerian techniques.
This course is intended for those who wish to understand the basic numerical methods for multiphase flows. The course is suitable for both postgraduate students and engineers and scientists in industry and government. Students with an engineering or mathematical background should have no difficulty in grasping the underlying principles of the methods and their applications to various fields.
