作者：Elghobashi，SE；萨缪尔森，GS；乌尔勒，JE；拉鲁，JC |摘要：本文讨论了反向流中射流的有限轴对称湍流非反应流中热量、质量和动量传递的测量和预测。通过数值求解平均流量守恒方程和湍流动能及其耗散率和均方温度波动的输运方程来获得预测。预测的速度场与实验一致，但预测的标量场表明需要检查所采用的标量湍流扩散模型。 © 1981 由 ASME 版权所有。
Author(s): Elghobashi, SE; Samuelsen, GS; Wuerer, JE; LaRue, JC | Abstract: The paper addresses the measurement and prediction of heat, mass, and momentum transport in a confined axisymmetric turbulent nonreacting flow of a jet in an opposing stream. The predictions are obtained by solving numerically the conservation equations of the mean flow and the transport equations of the kinetic energy of turbulence and its dissipation rate and the mean square temperature fluctuations. The predicted velocity field is in agreement with the experiment, but the predicted scalar fields point to the need of examining the employed model of a scalar turbulent diffusion. © 1981 by ASME.
