After the course, the student is able to...
- Explain / describe numerical modeling approaches of transport in turbulent flows
- Apply these modeling approaches in a commercially available CFD code
- Describe and analyse the behavior of chemical reaction mechanisms with many elementary reactions
- Describe and analyse the modeling of a chemical reaction in a turbulent flow process
- Solve numerically turbulent transport problems in process or power generation industry
The course targets the student to know about numerical modelling approaches of transport in turbulent flows, and how to use them in a commercially available CFD code. The student will know about, and how to analyse, turbulent flows with chemical reactions by means of models and numerical simulation. The student will be able to handle modeling off chemical reaction described by mechanisms with many elementary reactions. He will know how use and understand turbulent flow models in a RaNS and LES approach.. The student will learn how to characterize the regime of turbulent combustion on basis of dimensionless numbers such as Reynolds, Lewis, Prandtl, Schmidt and Karlovitz numbers.This knowledge will enable the student to solve numerically turbulent transport problems in for example the process industry or power generation industry.The course treats the transport in the turbulent flow of gaseous fluids composed of multiple species, by means of diffusion, convection or chemical reaction.|
Turbulence has a large effect on both convective transport and chemical reaction. The course intends to give an overview of the major processes, and a description by means of transport equations is presented. Numerical tools (Computational Fluid Dynamics) are used for product optimization and analysis. In the course several assignments in the use of numerical models for chemical reaction, turbulent convection and mixing and combustion will be given. The course will be finalized by means of a computer assignment using a CFD package made available to the students for use on their lap top computer. A practical case with application on a combustion problem will be worked out. The marking will be done on basis of the assignment reports and an oral exam.
