Abstract

tube heat exchanger used a delta airfoil array of turbulators in line configuration to investigate increased heat transmission and flow characteristics. The turbulence test was carried out. Numerous variables, such as pitching proportions, durations, and assault orientations, were tested in this experiment, but its influence on thermophysical properties was noted. The findings suggest that PR considerably affected both F and NU. In all cases where PR = 1.7, VGs had the highest f and Nu. At Re = 7000, tensor flow with L12 B45 PR4.9 achieved the highest TPE of 1.39. Assault direction B considerably influenced thermal efficiency, with a TPE of 2.45 at reduced Res. Fluid film flow or smoky movement visualization was used to locate vortices and explain flowing mechanisms. The lubricant film flow visualization with smoky movement tracked transverse swirl and generated swirl, which caused impact flow and a recirculating region, resulting in significantly enhanced heat transfer.
