Abstract

In wind tunnel testing the interference of the model mount with the flow needs to be investigated. The two different model mount configurations, tail sting and cross-stream rod, have been tested regarding their influence on the flow around a sphere at static incidence angles. The mechanic demands for unsteady force measurements determine the dimensions of the model mount and affect the support interference. In the paper a suitable mechanical design is presented. Further, the influence of the two configurations on crosswind is discussed by analyzing the side forces on a sphere at Re = 6.25 × 104 under different static incidence angles. It is shown that for this setup, a tail sting disturbs the wake flow in a non-correctable manner, whereas the results obtained for the cross-stream rod show good agreement with the literature. Hence, a cross-stream rod model mount concept is chosen for further testing on unsteady crosswinds.
