Corrected Correlation for Turbulent Convective Heat Transfer in Concentric Annular Pipes

Corrected Correlation for Turbulent Convective Heat Transfer in Concentric Annular Pipes

This paper addresses the errors that arise when calculating the convective heat transfer in concentric annular pipes by using the equivalent diameter and turbulent heat transfer formula for circular pipes. This approach employs numerical simulations to solve the Reynolds-averaged Navier–Stokes equat...
