Two-dimensional jet boundary interaction for submerged thermal discharges

A comprehensive theoretical and experimental study which investigates the jet-boundary interaction of a heated two dimensional jet discharging offset from and parallel to a solid wall is presented. The limiting case of a heated wall jet is also considered. An integral formulation of the conservation equations coupled with appropriate entrainment closure assumptions, provide for the solution of both the velocity and temperature fields, while accounting for the effects of ambient motion. The theoretical model is unique in that the base pressure and radius of curvature in the initial region of the jet are retained as variables. Various comparisons between predicted and measured values of velocity and temperature decay, maximum wall pressure, re-attachment length and recirculation region temperature were made. In general, agreement is good.
