Abstract

Turbulent flow at Reynolds number 50,000 around a sphere with trip wire placed 75° from the frontal stagnation point is investigated using detached eddy simulation (DES). The time-averaged results of the velocity field agree considerably well with the measurements from literature and reveal good reproduction of the separation zone, as well as the extent of the recirculation region. While the near-wall velocities are well captured, certain under-prediction of the values in the wake is observed.
