Title

Pressure Drop And Endwall Heat Transfer Effects Of A Staggered Array Of Porous Metal Pins

Abstract

This paper examines the local and averaged endwall heat transfer effects of a staggered array of porous aluminum pin fins with a pore density of 10 pores per inch (PPI). The pressure drop through the channel was also determined for several flow rates. Local heat transfer coefficients on the endwall were measured using Thermochromatic Liquid Crystal (TLC) sheets recorded with a charge-coupled device (CCD) camera. Static and total pressure measurements were taken at the entrance and exit of the test section to determine the overall pressure drop through the channel and explain the heat transfer trends through the channel. Results are presented for Reynolds numbers between 18000 and 100000 and a blockage ratio (blocked channel area divided by open channel area) of 50%. All results were compared to the corresponding results obtained using solid pins. All experiments were carried out in a 150 mm by 500 mm channel with an X/D of 1.72, a Y/D of 2.0, and a Z/D of 1.72.
