Summary
The course begins with a reminder of the benefits of modelling in multi-physical problems, particularly in the case of chemical reactors. The three digital simulation methods are then presented: finite differences, finite volumes and finite elements. The main modelling stages are covered in detail: the definition of the problem, geometric construction, boundary conditions, mesh, solvers and post-processing. The lecture portion ends with the management of boundary conditions for hydrodynamic and then turbulent models. Students work in pairs on COMSOL software during tutorials. An initial exercise makes it possible for students to familiarise themselves with the interface of the code and to simultaneously make calculations by hand and with the code on a simple problem (thermal/electrical coupling on a conductor surrounded by plastic sheathing). Then several flow problems are handled with increasingly complex geometries (simple reactors, dissymmetrical reactors, baffle reactors, helix reactors) and the transfer function is calculated. The laminar approach is complemented by a k-epsilon turbulence model. The influence of the mesh is tested. Lastly, Navier-Stokes couplings with thermal systems conclude the tutorials.
Educational goals
At the end of this course, students should: 1/ better understand the different stages of digital simulation as well as its limitations. 2/ be able to use the COMSOL calculation code for calculations requiring couplings. 3/ calculate a transfer function of a hydrodynamic reactor.
