Description The Reynolds' analogy between the Stanton number (St) and the skin friction coefficient (c(f)) is popularly believed to hold when St increases with increasing c(f), for simple situations. In this investigation, the validity of Reynolds' analogy between St and c(f) for micro-convection of liquids with variations in fluid properties is re-examined. It is found that the Sieder-Tate's property-ratio method for obtaining Nusselt number corrections is theoretically based on the validity of Reynolds' analogy. The inverse dependence of Reynolds number and skin friction coefficient is the basis for validity of the Reynolds' analogy, in convective flows with fluid property variations. This leads to the unexpected outcome that Reynolds' analogy now results in St increasing with decreasing c(f). These results and their analyses indicate that the validity of Reynolds' analogy is based on deeper foundations, and the well-known validity criterion is a special case.
