Highly accurate numerical solution of the Navier-Stokes equations in pipes


The acoustic characterization is one of the key challenges in engineering exhaust systems of vehicles. In the seminar, I will present a numerical study of the exhaust gas flow both in the pipe of a simplified exhaust system and in the exhaust jet. The acoustic noise stems primarily from the highly turbulent fluid flow. To resolve eddies in the turbulent flow up to the levels required for acoustic characterization, Large Eddy Simulation is applied. The simulation results are also compared to experimental measurements.
