| There are numerous processes of practical importance in both the environment and in the industry that involve complex multiphase/multicomponent flows. Separation and mixing of particles, cavitation, boiling are classical examples of such industrial problems. The available computer capacity enables the numerical (CFD) modelling of such complex processes. A few examples will be presented in the talk to demonstrate some up-to date CFD models. More will be said about several physical and engineering aspects of boiling. As a case study we shall present in detail the numerical model of a large evaporator used in the nuclear industry. The physical processes to be modelled include, flow through tube bundles, heat transfer, boiling and recondensation, gravity-driven flow, free surface motion. Results for the advection and settlement of suspended contaminants are presented, as well. |
