000004238 520__ $$2eng$$aAn extensive set of impinging jet experiments have been recently performed at the Boundary Layer Wind Tunnel Laboratory in order to clarify the Reynolds number (scale) and surface roughness effects in impinging jet flows with application to downburst simulations. Clarification of these two aspects is essential in designing proper laboratory experiments as well as in their extension to full scale results. The velocity field has been found to be scale dependent with the depth of the boundary layer formed on the impinging surface being Reynolds number dependent until a critical Re value. Above the critical Reynolds number the boundary layer depth shows almost constant value which increases only with roughness height.
