SIMULTANEOUS TRANSFER OF MOMENTUM HEAT AND MASS. PART III. EVAPORATIVE COOLING AT HIGH SPEED

Abstract

The opposite effects of evaporative cooling and of aerodynamic heating at high speed are investigated. The evaporative cooling is a very effective process to strongly reduce the friction heating produced by high speeds. The wet bulb of a psychrometer describes the adiabatic case of evaporative cooling. The field of low vapour concentration is thoroughly analyzed and simple graphical methods are derived. Numerical examples illustrate the obtained results. The stability of laminar flow under evaporative cooling is eventually discussed. (Author)
