Experimental study of heat transfer natural convection in horizontal internally finned tube

A simplified model of the tube heat exchanger is used to experimentally study the thermal impact of using four internal fins fixed to the diameter inside tube heat exchanger. This model consists of a heated horizontal cylinder with a constant heat flux placed around the cylinder. The project also us...
