Surface tension to density ratio is tested using three fluids namely water, ethylene glycol and R-141b. Results show that flooding was strongly effected by changing the condensate flow rate. An increase in flow rate caused a marginal decrease in flooding angle an angle extracted from top of the test tube to the fully flooded flank). Similarly, circumferential pin-spacing also effected the retention angle and the effect goes on increasing by decreasing the surface tension to density ratio. © 2018 Serbian Society of Heat Transfer Engineers. publisher: Serbian Society of Heat Transfer Engineers date: 2018 type: Article type: PeerReviewed identifier: Ali, H.M. and Ali, H. and Abubaker, M. and Saieed, A. and Pao, W. and Ahmadlouydarab, M. and Koten, H. and Abid, M.
