Heat Transfer from Low Aspect Ratio Pin Fins
… gas turbines is limited by thermal management. Pin fins are commonly used to augment heat transfer by increasing surface area and increasing turbulence. The present research is focused on but not limited to internal cooling of turbine airfoils using pin fins. Although the pin fins are not …

Heat Transfer from Multiple Row Arrays of Low Aspect Ratio Pin Fins
… heat transfer characteristics through arrays of pin fins were studied for the further development of internal cooling methods for turbine airfoils. Low aspect ratio pin fin arrays were tested through a range of Reynolds numbers between 5000 and 30,000 to determine the effects of pin spacing as …

Development of a Methodology to Measure Aerodynamic Forces on Pin Fins in Channel Flow
… promise in both of these industries. Although pin fins are often placed in the cooling channels to augment heat transfer, their addition comes at the expense of increased pressure drop. Consequently, the pin fin geometry must be judiciously chosen to achieve the desired heat transfer rate while …

Design of an isolated, quiet, universal ATX computer case
… from the hard disk. A universal CPU cooler uses pin fins with forced convection an custom adapter plates to mate with a variety of CPU processors. It is capable of dissipating 162 W, more than any CPU on the market needs. This is all accomplished without exceeding any surface temperature limit of …

Development of Advanced Internal Cooling Technologies for Gas Turbine Airfoils under Stationary and Rotating Conditions
… The leading edge is typically cooled by jet impingement which cross-over the rib turbulators in the feed chamber. The mid-chord section of the turbine airfoils have serpentine passages connected via. 180° bends, and they feature turbulence promotors which enhance the heat exchange rates between …

Numerical and Experimental Design of High Performance Heat Exchanger System for A Thermoelectric Power Generator for Implementation in Automobile Exhaust Gas Waste Heat Recovery
The effects of greenhouse gases have seen a significant rise in recent years due to the use of fossil fuels like gasoline and diesel. Conversion of the energy stored in these fossil fuels to mechanical work is an extremely inefficient process which results in a high amount of energy rejected in the …
