Investigations of flow and heat transfer of multiphase, multicomponent fluid mixtures are the subject of significant research teams in the field of experimental and numerical fluid dynamics, as well as applied fluid dynamics. The work process efficiency and safety of many industrial plants is based on knowledge of fluid flow, mass and heat transfer, and thermo-hydraulic parameters of the fluid mixture. Department of Thermal Engineering and Energy at Institute of Nuclear Sciences VINČA is involved in developing different computational models of various complex types of flows which have application in the thermal, process and chemical industry, but also in the energy sector, food industry and medicine. The Computational Fluid Dynamics numerical models are based on the Navier – Stokes equations. Three numerical models are presented: Computational study of the two – fluid nozzle spreading characteristics, Numerical study of the hydrodynamics and mass transfer in the external loop airlift reactor and CFD modelling of the two phase flow and heat transfer in vertical steam generator using different flow models. Different types of multiphase models are used: Volume of fluid (VOF) models, mixture models and the Eulerian group of numerical methods. Numerical methods are validated with appropriate experimental results and/or appropriate computational models.
