The trajectory of a heated, buoyant jet in a non-uniform cross-flow
Abstract
A method is described to determine the path taken by a jet injected at an angle into a cross flow. The empirical correlation between the variables in the flow is used to predict the jet path, the center line velocity and temperature at injection angles up to a moderate forward inclination. Allowance is made for temperature and density differences and for nonuniformities in the cross flow. The equations are solved by a fourth-order Runge-Kutta routine in a VAX-11 computer. The examples show that the method produces reliable results within its expected regime even with the jet directed 30 deg forward. Buoyancy effects need to be calibrated.
