About

With about 20 scientific employees and students, the Institute for Reactive Flows of the University of Stuttgart conducts research on the fundamentals of modelling and simulation of turbulent, reacting flows in the areas of multiphase flows (gaseous/liquid and gaseous/solid), chemical reactors and nanoparticle processes. The teaching of IRST covers the fundamentals and advanced topics in reacting flow systems, simulation methods as well as related programming basics.
