Abstract

An experimental investigation has been carried out on the heat transfer characteristics of a turbulent, negatively buoyant, two-dimensional wall jet. The heat transfer to the surface from the jet, the discharge temperature of which is taken as greater than the surface temperature, is measured as a function of distance along the isothermal surface for several values of wall, jet and ambient temperatures. It is found that the total heat transfer rate to the isothermal vertical surface decreases with an increase in the mixed convection parameter. The effect of the surface temperature excess on the downward penetration of the jet and on the heat transfer rate is also investigated. Relevant correlating equations are derived.
