Flow Resistance Characteristics of De-ionized Water Flow through Staggered Diamond and Circular Micro Pin Fin Arrays

摘要：

This paper reports an experimental investigation on flow resistance characteristics associated with the forced flow of de-ionized water through circular and diamond shaped micro pin fin arrays. Comparing with circular pin fin arrays, diamond shaped pins produce higher friction factors. By comparing the current data with results available in the literature, it can be concluded that the conventional long tube correlations are unable to predict the friction factor for micro pin fin arrays. According to the experimental data, several new correlations for friction factor and Reynolds number of staggered pin fin arrays were developed.
