Summary

USING THE PRINCIPLE OF NEWTONIAN HEATING, A NOVEL EXPERIMENTAL PROCEDURE HAS BEEN DEVELOPED FOR THE DETERMINATION OF THE INSTANTANEOUS HEAT TRANSFER COEFFICIENTS AND MASS TRANSFER RATES AND THEIR DEPENDENCE ON TIME. TESTS WERE MADE ON A PRECOOLED CYLINDER OF NEGLIGIBLE THERMAL RESISTANCE IN A CROSS FLOW OF HUMID AIR OVER A REYNOLDS NUMBER RANGE 9,300-22,200. PROVISIONAL COMPARISON WITH PREVIOUS DATA FOR CONDENSATION IN THE STEADY-STATE CASE HAS BEEN MADE AND INDICATES THAT THE PROPOSED METHOD MAY PROVE A VALUABLE ALTERNATIVE TO THE STEADY-STATE TECHNIQUE OF MEASUREMENT IN THIS AREA OF STUDY.
