Impingement Heat Transfer over a Rotating Disk: Integral Method

摘要

An integral method was developed, and an approximate analytical solution of the problem was derived at n~* = -2 ... 4. Maximal deviation of the approximate solution from the exact one is 2.4%. At κ > 1.5 heat transfer is dominated only by peculiarities of the impinging jet. The threshold value of κ is practically independent of Pr and exponent n~*. Present predictions agree well with experiments in the vicinity of the stagnation point.
