Numerical analysis on thermal performanace of staggered pin-fin assembly

Steady state heat transfer and friction characteristics and performance analysis for flow through a rectangular channel with heat sinks of circular cross-section pin fins in turbulence flow was studied in the present study. The heat sink was immersed in the channel with fluid flowing at constant inl...
