WebFORCED AND FREE CONVECTION 10.1 Introduction • A key factor in convection is the heat the heat transfer coefficient h. • Instead of determining h we determine the Nusselt number Nu, which a dimensionless heat transfer coefficient. • Whenever it is difficult or not possible to determine the Nusselt number analytically, WebForced convection heat transfer from an isothermal heated cone (apex up and down) in Bingham plastic fluids has been studied numerically. Extensive results are presented here in terms of isotherm and Nusselt number over ranges of conditions as: Reynolds number, 1≤ Re ≤100, Prandtl number, 10≤ Pr ≤100, Bingham number, 0≤ Bn ≤100 and cone angle, …
