FLOW VISUALIZATION AND COMPARISON OF THE EVAPORATION HEAT TRANSFER COEFFICIENT FOR SMOOTH AND ENHANCED SURFACE 1EHT HORIZONTAL TUBES

by vipertex on September 14th, 2015

Flow visualization of flows near a heat transfer tube and evaporation heat transfer results of Vipertex 1EHT tubes are compared to  Smooth Tubes have been presented  at ECCE10 (10th European Congress of Chemical Engineering).
