Abstract Thermal performance enhancement in a square channel heat exchanger (HX) using a passive technique is
presented. Vortex turbulator insertion in a square channel HX as a passive technique is selected for thermal
improvement. The vortex turbulator of interest is discrete X-V baffles (XVB). The discrete XVBs are inserted in the
square channel with the main aim of generating vortex flow. The vortex flow generated can support the enhanced
convective heat transfer coefficient and also enhance HX performance. Effects of baffle configuration (type A and
B), baffle size (w/H = 0.05, 0.10, 0.15 and 0.20), baffle… More >
