This equipment demonstrates the different regimes of pool boiling. In the test section, a test wire is surrounded by water maintained at a constant temperature. When current is passed through the wire, its surface temperature increases. As the temperature difference between the wire surface and the surrounding water increases, the various boiling regimes are observed until the burnout point is reached.

Experimental Objective

·        To plot the graph of heat flux versus bulk temperature up to the burnout (critical) condition.

·       To study boiling heat transfer phenomena and determine the critical heat flux in pool boiling of water.
