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. {\^A}{\copyright} 2018 Serbian Society of Heat Transfer Engineers.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85057091042&doi=10.2298\%2fTSCI171129161A&partnerID=40&md5=b2e89d0983f4582cf40f16147a95e31b} }
