Heat exchangers are vital components of industry and plants, and their system and design demand for a high level of technical expertise. Nevertheless, this information is split over a number of sources, including books, journals, standards, and industrial regulations. The purpose of this study is to examine the effects of utilizing a porous density (PD) twisted tape insert in place of a standard twisted tape on heat transfer performance. It is assumed that the fluid flow is turbulent, incompressible, and steady. The energy loss resulting from fluid motion is disregarded, but the flow and heat transfer processes are thought to be fully developed. The twisted tape inserts in the trial will have a twist ratio of 10 and a Reynolds number range of 5,000 to 12,500. There will be three distinct densities of perforations in the twisted tape geometry. SolidWorks was used to create the solid model's geometry, while ANSYS was used to create the fluid model and perform the simulation. The objective was to evaluate the hydrothermal performance of porous density twisted tape inserts with varying perforation ratios in the tube, ranging from low to high density, in comparison to normal twisted tape.
