Experimental Study of Condensation Characteristics on a Vertical Plate Covered with Metal Foam

Abstract

Metal foam (MF)-coated plate possesses the advantage of big surface area, thus it has great potential for improving the plate condensers' condensation Heat Transfer (HT). In the current research, the pores density influences of Copper Foam (CF) upon a Flat Plate (FP) with (CF) attached have been studied experimentally. And, the CF pore density conceals the utilized plate structure, which ranges from 10 PPI to 20 PPI, and the porosity of 90%. The feature of flow water steam in CF coated plate is presented by using coefficient method of unit mass efficacy. Also, the pore's density influences of CF size, rate of the mass flow of inlet steam water, and rate of the mass flow of cold water upon the HT and Pressure Drop (PD) have been tested and analyzed. The correlations of HT and  for a vertical Flat Plate (FP) with fixed CF are determined the curve-fitting of the investigational values. Additionally, the result elucidated that the CF introduction improves the HT despite causing a bigger . A (10 PPI) sized CF reveals a higher performance. It is also observed that the higher pressure of inlet steam, the higher rate of the mass flow of steam and the lower temperature of cold water will result in the increase of the average Heat Transfer Rate (HTR).
