LARGE-EDDY SIMULATIONS OF PLANE IMPINGING JETS

The methods used for the study of the impingement of a thermally inhom ogeneous plane jet on a solid plate. using large-eddy simulation, an d escribed. Innovative numerical methods have been introduced to produce the thermally inhomogeneous jet, to study the transmission of thermal fluctuations into the solid plate, and to prevent overshoot in the th ermal computation. We have studied the impingement of water on a persp ex plate in three different geometries, and also one case of the impin gement of liquid sodium on a steel plate. Comparison is made with avai lable experimental data and closure calculations.
