| Summary: | affixed to the two primary walls. The deflector plates are air toward the top and bottom primary walls alternately. The angle-of-attack gives the best thermal performance at the array with the deflector plates at 45' angle-of-attack attack of 15', 30', and 45', and five flow rates. Results bottom wall of the channel is heated by passing electrical change color over a specific temperature range. Experimental channel with periodic longitudinal deflector plates that are current through a thin Inconel foil that is attached to the enhance heat transfer the most at all tested mass flow rates. Experiments are conducted to study turbulent steady state heat transfer and friction for airflow in a wide rectangular heater is indicated with thermochromic liquid crystals, which inner surface. The temperature at the surface of the foil lower mass flow rates, while the same array at 45' fin angle- lower pressure drop but does not increase heat transfer as mass flow rates. The array with the larger pitch causes much as the array with the small pitch. of-attack produces the best thermal performance at the higher results are obtained for two fin pitches, three angles-of- show that the deflector plate array with a smaller pitch is staggered and are oriented such that they deflect the flow of superior to that with a larger pitch. The smaller pitch The smaller pitch array with the deflector plates at 15' |
