Experimental Investigation of Vertical Downward Flow Boiling Heat Transfer inside Horizontal Mini Rectangular Channel
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 8
Abstract
The present work is carried to determine the two phase heat transfer coefficient during flowing vertical downward in the minichannel. The minichannel test section is made up of aluminum having hydraulic diameter 1.33mm. The experiments were carried out by varying mass flow rate from 0.1g/sec to 0.3g/sec of steam at three different vapour qualities of 0.2, 0.4 and 0.6. The result showed as the heat flux increases there is an increase in two phase heat transfer coefficient upto 20000W/m2 0C. In addition to that there is a decrease in treand of heat transfer coefficient for vapour quality.
