Effect of Nozzle Shaped Triangular Longitudinal Fins on Heat Transfer

Experimental study of heat transfer and thermal performance with longitudinal fins of solar air heater

The thermal performance of a single pass solar air heater with five fins attached was investigated experimentally. Longitudinal fins were used inferior the absorber plate to increase the heat exchange and render the flow fluid in the channel uniform. The effect of mass flow rate of air on the outlet temperature, the heat transfer in the thickness of the solar collector, and the thermal efficien...

Effect of Staggered Fins on Heat Transfer and Pressure Drop in Heatsinks

The performance of a heatsink with and without staggered fins is analyzed in the present work. The effect of flow resistance on thermal behavior of staggered plate heatsinks were analyzed in the present study. Ansys FLUENT has been used for the present simulation. Authors have used three different models with and without staggered arrangement. The result shows advantage of staggered heat sink o...

The Solar Air Channels: Comparative Analysis, Introduction of Arc-shaped Fins to Improve the Thermal Transfer

The problem under investigation contains a computational simulation of a specific heat exchanger with complex geometry fins. The problem solved is potentially interesting for researchers and engineers working on solar collectors and aerospace industry. It is known that heat transfer enhancement can be achieved by creating longitudinal vortices in the flow. These vortices can be generated by arc...

CuO/ Water Nanofluid Heat Transfer Through Triangular Ducts

Numerical simulation of laminar convection heat transfer from an array of circular perforated fins

The present paper reports the laminar fluid flow and heat transfer of a heated array of circular-perforated and solid fins mounted over a flat surface using the finite-volume method. One to four circular cross-sectional perforations are made along the length of the fins. The SIMPLE algorithm is used for pressure-velocity coupling and the second order upwind technique is employed to discreti...
