![]() It also helps in enhancing the convective heat transfer through a fluid layer relative to conductive heat transfer for the same fluid. Thisrelates in-between convective and conductive heat transfer for the similartypes of fluids. X = distance from the boundary surface Significance of Nusselt number. The Local Nusselt Number is represented as K = the thermal conductivity of the fluid. Where h = convective heat transfer coefficient of the flow Nu = Convective heat transfer / conductive heat transfer Nusselt number equation | Nusselt number formulaĪverage Nusselt Number can be formulated as: The surface will be normal of the boundary surface, and vertical to the mean fluid-flow.The convection and conduction heat flows in-parallel to each other.“The Nusselt number is the ratio of convective to conductive heat transfer across a boundary.” Content: Nusselt Number What is Nusselt number | Nusselt number definition
