For three-dimensional stagnation flow of fluids with Pr ≈ 1 on an axi-symmetric blunt body, the following correlation can be used for predicting the heat transfer coefficient at the vicinity of the stagnation point (Reshotko and Cohen, 1955):

Derive an expression for heat transfer coefficient at the immediate vicinity of the stagnation point of a sphere.
