A critical re-examination of Reynolds analogy for micro-convective flow

The present research numerically investigates the validity of Reynolds analogy for micro-convective water flow between Stanton number (St) and Fanning friction factor (ff), taking into account combined fluid properties variations such as temperature-dependent density, viscosity, thermal conductivity. is suggested to be valid when St increases thermophysical (TFP) with a decrease in ff. This analogy, therefore, helps find regime that heat transfer while shear stress decreases TFP. Hence, TFP design improve performance different devices, including micro-scale exchangers electronics cooling, internal cooling passages turbine airfoils, many biomedical devices. Three modified non-dimensional parameters (ΠSρT, ΠSμT, ΠSkT) appear from non-dimensionalization governing conservation equations. Using dimensional analysis, dependence on these examined.
