Analysis of a heated jet in a stream

Abstract

A plane, heated jet of a constant property fluid exiting into a plane, straight channel of the same fluid is analyzed. The effect of buoyancy on the velocity and temperature fields is investigated. Two jet orientations are considered; a transverse jet, which enters the stream perpendicular to the main flow, and a longitudinal jet, which enters the stream parallel to the main flow. Solutions for the temperature and velocity fields for low Reynolds number flow are obtained using a finite difference scheme. Results are presented for three different values of the buoyant force, holding other variables constant. For an isothermal jet, results for the velocity field are presented at a higher Reynolds number.
