Abstract Simulated examinations on convective heat transfer and flow topology in a square duct heat exchanger placed with wavy thin rib (WTR) are
presented. The influences of WTR heights, pitch distances and flow directions on flow and heat transfer characteristics are investigated for the
laminar flow regime at the inlet condition (Re = 100 – 2000). The finite volume method (SIMPLE algorithm) is picked to analyze the numerical
problem. The numerical validations; grid independence and verification of the smooth duct, are presented. The simulated results of the heat
exchanger duct placed with WTR are reported in terms of flow and heat… More >
