Abstract

Calculations using a second-order algebraic stress model are compared with wind tunnel and full-scale measurements for flow over a two-dimensional obstacle. The experiments show mutually good agreement. Outside the cavity, i.e. in front of the obstacle and at a distance of five obstacle heights downwind, calculations and experiments yield the same velocities and turbulent kinetic energies. However, in the cavity comparison is poor. This is caused by systematic errors in the anemometers. Therefore, it is the measurements in the cavity which are inaccurate and not the calculations.
