Abstract
Computations were performed to study the three-dimensional turbulent flow and heat transfer in a rotating narrow rectangular channel with staggered arrays of pin fins. The channel aspect ratio is 10:1, the pin length to diameter ratio is 1.0, and the pin spacing to hydraulic diameter ratio is 3.0 in both the streamwise (SL/Dh) and spanwise ST/D h) directions. Various combinations of rotation numbers and coolant-to-wall density ratios were examined. A total of seven calculations have been performed with various rotation numbers and inlet coolant-to-wall density ratios. The rotation number and density ratio varied from 0.0 to 0.14 and from 0.1 to 0.40, respectively. The Reynolds number is fixed to 10,000. A finite volume code, FLUENT is used to predict the flow and heat transfer. The Reynolds stress model in conjunction with a two-layer model is used to compute the turbulent flow and heat transfer in the rotating channel. The computational results are in good agreement with experimental data.
