Design and CFD Simulation of Heat Transfer in Circular Pipes

A major issue for human growth is the energy crisis. In the current study, circular pipes are considered an energy-efficient technology viable in all seasons. It uses non-constant soil temperature and water flow in coldest regions. This model reports the thermal performance of pipes with different results in hot and cold climates. To degree thermal performance, pipe version changed into advanced and simulated with ANSYS 18.1 Fluid Flow (Fluent). Data was collected from two modelled summer and winter seasons. Continuity, momentum, and energy equation have been used for the simulation. Comparison analysis is also being carried out about the obtained results with previously published articles. The effects of summer and winter temperature and speed on performance were also evaluated. Further, the graphical interpretation is also carried for velocity and pressure distribution. The study highlights a drastic drop in temperature and velocity near the inlet and outlet region while Pressure is inversely proportional to velocity in these regions. It is also obtained from the simulation that the temperature pressure and velocity remain uniform in the fully develop region.
