Numerical study of thermal performance of perforated circular pin fin heat sinks in forced convection

摘要: This paper presents a numerical simulation of the heat transfer performance under forced convection for two different types circular pin fin sinks with (Type A) and without B) hollow in heated base. COMSOL Multiphysics, which is used thermal hydraulic analyses, has proven to be powerful finite-element-based tool solving multiple physics-based systems partial ordinary differential equations. The standard \( \kappa - \varepsilon \) two-equations turbulence model employed describe turbulent structure behavior. results are validated experimental results, shown good agreement. effects Reynolds number, height fin, finning factor perforated base plate on heat-transfer coefficient investigated evaluated. present study strongly recommends use small (\( (D_{h} /D_{b} ) < 0.15 \)) constructed sink.
