The experimental and numerical studies of thermo-hydraulic characteristics perforated wavy fin heat exchanger unperforated were conducted. Firstly, the two kinds fins studied under different air in?let velocity constant inlet temperature. results show that Nusselt number increases with Reynolds friction factor decreases number. Then, performance is numerically analyzed, simulation are in good a...

The current work explores a trial forced convective heat move from rectangular blades on an upward surface at low Reynolds numbers. removal for proper number of punctured and non-punctured fins, fin dividing, length was estimated in air stream fluctuating inlet speed some way or another info power somewhere the range 20W 70W. characteristics are investigated rectangular, circular, V-shape perfo...

Heat sinks are widely adopted in electronics cooling together with different technologies to enhance the cooling process. For the small electronics application, the small scale pin fins heat sinks are extensively used to dissipate heat in electronics devices. Due to the limit of space in the small devices, it is impossible to increase heat transfer area. In order to improve the heat transfer pe...

This research attempts to investigate the thermal performance of solar air collectors with pin fins and turbulators. Incorporating carbon-nanotube-based turbulators in can enhance their due high conductivity, low weight, aspect ratio. In present study, numerical analyses a collector are carried out its effect on Nusselt number. The paper begins analysis conventional compares them theoretical re...
