Experimental Investigation of Pool Boiling: Effect of Microscale Roughness

Abstract

This research paper tells about the how the surface characterization can affect the boiling heat transfer. Enhancement of pool boiling performance have been recognized as a critical thing to increase the performance of the boiling heat transfer by the ideal surface geometries. Instead of that this experiment was performed on the different roughness such as 1000 and 1200 grades of emery paper. Majorly, Copper polished surfaces are used to enhance the heat transfer coefficient in the two-phase heat transfer method. X-ray diffraction, scanning electron microscopic (SEM) are used to study the surface engineering. Increasing the thermal conductivity is one of the major problems in the field of thermal science and energy engineering. So, finally we can get the enhancement in boiling performance and also the increase of the critical heat flux and the heat transfer coefficient when the surface roughness is decreased.
