<p><i>In this paper, the numerical effect of increasing the heat transfer coefficient of forced displacement of Nano fluids Tio2 in heat and cold pipe, under constant heat flux placed around the pipe is compared to that of a circular straight pipe. Collision with the pipe steps disrupts the thermal boundary layer and this increases the heat transfer coefficient of the fluid flow displacement. The results show that inside the pipe it increases the turbulence with the fluid flow along the transverse, which eventually creates A good mixing in the flow causes the temperature profile to be flatter and the thickness of the thermal boundary layer to decrease, which in turn increases the heat transfer coefficient. Therefore, by increasing the volume of Nano fluids by 4% and examining hot and cold pipes compared to simple pipes, and using Nano fluids in hot and cold pipes and optimizing it by 7/8%, it has been fixed under heat flux</i></p>

ASME 2021 Fluids Engineering Division Summer Meeting (FEDSM2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
