Abstract

In this study, the accuracy of the convective heat transfer coefficient was verified using a velocity scale based on wall shear stress using the boundary-layer theory, which has long been confirmed to be accurate for in-pipe flows. The inside of the pipe was modeled analytically and a heating surface was assumed to satisfy the assumed conditions of the boundary-layer theory. The reference temperature for the convective heat transfer coefficient was defined as the dimensionless distance y+, and a parameter sensitivity analysis was performed along with mesh partitioning to determine the best solution.
