Abstract Simulation of fluid-flow topology and thermal behavior in a round tube heat exchanger (RTHX) installed by three
V-rib sets is reported. The expected phenomena for the rib installation are the generated vortex flow, impinging
flow, greater fluid blending and thermal boundary layer disturbance (TBLD). These phenomena are key causes
of the augmentation of heat transfer potentiality and thermal efficiency of the RTHX. Effects of rib height (b1
= 0.05D – 0.25D and b2 = 0.05D – 0.25D), rib pitch or rib spacing (P = D, 1.5D and 2D) and fluid directions
(positive x (+x flow direction) and negative x (–x… More >
