Distribution of Temperature as a Passive Scalar in the Flow Field of a Heated Turbulent Jet in a Crossflow

This article presents a computational investigation of the mean flow field of heated turbulent rectangular jets in a crossflow. The jet is discharged with a slightly higher temperature (about 6°C) than the crossflow. The computations are carried out for two values of jet-to-crossflow velocity ratio,...

Description
Summary:This article presents a computational investigation of the mean flow field of heated turbulent rectangular jets in a crossflow. The jet is discharged with a slightly higher temperature (about 6°C) than the crossflow. The computations are carried out for two values of jet-to-crossflow velocity ratio, 6 and 9. The commercial code FLUENT 6.2.16, employing the Reynolds stress transport model, is used to predict the mean flow field. The influence of the velocity field on the temperature distributions is discussed. A comparison of the predicted results is made with the available experimental data, and reasonably good agreement is observed.
