Numerical investigations of a turbulent flow over triple forward facing step

In this paper, the turbulent flow over a triple forward facing step configuration was investigated numerically. To that end, numerical simulations are performed for 4 Re numbers and 36 different geometries. Turbulence is modeled in all simulations using the Standard k-¿ model. The resulting flow field is examined in terms of pressure coefficient, vorticity and turbulent kinetic energy. Furthermore, statistical analysis are performed on the results to reveal the quantitative effects of varying the Re number and geometric parameters on the resulting flow field.
