AB - The extent of condensate flooding as a function of condensate flow rate is  measured on six horizontal pin-fin tubes (varying in circumferential pin-16  spacing) via simulated experimentation. 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.
