Experiments were performed to determine the heat transfer characteristics of a turbulent pipe flow downstream of a flow control orifice. The orifice consisted of an orifice plate followed by an abrupt expansion. A total of fifty-four geometric variants were tested. The working fluid was water, with Prandtl number 7, and the Reynolds number range was from 50, 000 to 125, 000. The maximum Nusselt numbers observed were 3 to 5 times the value for the corresponding fully-developed flows. © 1982.
