The learning content includes the general setting up of balance equations. In particular, the balancing of mass, momentum and energy for solving flow problems is also dealt with. For this purpose, an understanding of the discretisation of flow spaces must also be conveyed. For the description of turbulent flows, the balance equations are time-averaged and turbulence models are discussed. The equation systems are extended to two-phase systems (Euler-Lagrange). Furthermore, reaction equations and conservation equations of species for homogeneous and heterogeneous reactions are worked out. Based on this, conservation equations for heat transport in the form of heat conduction and heat radiation in reacting flows are established. Finally, the fundamentals of the numerical solution of equations/systems of equations are taught.
Examples for CFD applications: simple mixing processes (mass, momentum and energy), homogeneous and heterogeneous reactions (using the example of biomass pyrolysis), heat conduction using the example of an electric water heater, heat radiation using the example of an engine combustion chamber.
The students should be enabled to understand effects and phenomena of flows and their implementation in mathematical models and to apply them in situations of energy conversion systems. This includes the basics of fluid mechanics, mathematical modelling of flow processes in general, reactions, heat transfer and numerical solution of the descriptive equations.
