| Abstract | ||
| The purpose of this investigation is to determine if adding an isolated cylinder to the domain can improve forced convection in the laminar case of the sudden expansion flow in a two-dimensional channel. The range of the Reynolds number (1-200) and the number of prattle 0.71, the impact of different cross-stream locations (x=10.4,10.8 and 11.2) of the circular cylinder on the flow, and thermal properties of the sudden expansion flow have been computationally studied (air). COMSOL Multiphysics is utilized to address the governing continuity, Navier-Stokes, energy equation of energy, and the necessary boundary conditions. Although streamline and isotherm profiles have been used to describe the flow and thermal fields, the temperature dependence of the flow viscosity and thermal conductivity has not been taken into account. The findings presented here demonstrate an improvement in the peak Nusselt value when a circular cylinder is used in comparison to the unobstructed condition. | ||
