B}, month = {Jan}, note = {Heat transfer downstream of a backward-facing step was controlled using a jet discharged flow from a slit in the duct wall opposite the step. The local heat transfer coefficients were measured for various jet locations, jet velocities and duct expansion ratios. The reattachment region moves upstream and the heat transfer coefficients, which are maximum, increase with jet velocity. The coefficients also increase with the expansion ratio, but to a lesser extent. With appropriate change of the downstream coordinate, the many heat coefficient profiles under various conditions may be normalized to produce a single characteristic curve. The average heat transfer over the peak in each case can be expressed as a function of its maximum., 論文}, pages = {248--254}, title = {噴流による後ろ向きステップ下流の再付着領域の熱伝達特性の制御に関する研究 : 第2報,流路拡大比を変えた場合について}, volume = {60}, year = {1994} }
