Experimental Investigation of Liquid film falling on the horizontal circular cylinder
The rate of heat transfer that exists between falling liquid film and horizontal cylinder is generally high, for this reason, intertube falling-film heat transfer behaviour is widely used several industrial processes. This study is to experimentally investigate behaviour of falling film flow over the horizontal cylinders. When a liquid film falls from one tube to another below it, the flow can take the form of discrete droplets, individual jets or continuous sheet. Especially experiments exploring the effects of thermo physical properties and geometrical parameters on the droplet and jet flow patterns are described, because the two flow patterns are mostly important in heat transfer behaviour and less research directed at heat transfer for the two flow modes. Using experimental device we simulate the flow modes to compare with present experimental result from the literature. The primary objective of the present study is to solve the ambiguity that the effect of liquid flow rate, tube diameter and tube spacing on departure site spacing in drop and jet mode, in order to help developing the criteria for determining the falling film modes and their transitions, and understanding the heat transfer characteristics associated with each falling-film mode.
