Investigation of the Predictive Ability of Two Advection Schemes on the Formation of a Turbulent Separation Bubble in a Boundary Layer Wind Tunnel

Abstract:

This paper presents a study that correlates the capacity of two advection schemes in foreseeing flow separation inside a boundary layer wind tunnel (BLWT herein after). The geometry of the BLWT forces the generation of a turbulent separation bubble. Numerical simulations were carried out with the commercial Computational Fluid Dynamics software ANSYS-CFX^®. The high-resolution advection scheme is shown to be more appropriate than the upwind scheme in predicting flows where properties are subject to strong gradients, such as pressure and velocity.
