Synopsis:

Numerical modeling and simulation of fluid flow, heat and mass transport focused on practical problems in process engineering. ANSYS CFD will be used for geometry description, computational mesh and numerical solution. Several problems will be solved during the course, like fluid flow in a pipe network and pressure drop calculation, laminar or turbulent flow in a heat exchanger with total heat transfer coefficient evaluation, and fluid flow in a mixed system including chemical or biological reaction.
