... to dual clearances on cylindrical pin fins, relative to a channel between parallel plates, in mini/microchannel reactors at low Reynolds numbers. In this work, diffusion limitations to heat and mass transfer in smooth-walled mini/microchannel reactors were minimized by the implementation of microcylinder...

... that careful consideration be given to the performance of the pin fin geometries at low Reynolds numbers. Peles et al. ( 12 ) studied the heat transfer and pressure drop over a bank of micropin fins, derived an expression for the thermal resistance, and concluded that micropin fin heat transfer to be a very...

...Ali Rozati; Danesh K. Tafti; Neal E. Blackwell Cylindrical pin fins with tip clearances are investigated in the low Reynolds number range 5 < Re D < 400 in a plane minichannel. Five tip gaps are investigated ranging from a full pin fin ( t * = 0.0 ) to a clearance of t * = 0.4 D * , where D...
