An experimental study of turbulence in a density-stratified shear flow

摘要: This paper concerns an investigation of turbulence in the density stratified shear flow a specially designed wind tunnel which gradient is created by differential heating air. The first three sections consist description apparatus and mean temperature velocity gradients tunnel, together with discussion method measuring low speeds based on periodic shedding vortices circular cylinder. In remaining details experimentally determined structure its eddy conductivity viscosity are presented their dependence over-all form Richardson number, , considered.
