Comments on the convergence of finite element solutions

Abstract

(Uc ~ UJ/(Ui tfco) oc i/x This result indicates that there is a possibility to define the proportionality constant such that the flow will be selfpreserving. Applying the transformations reported for the stagnant external conditions did not yield the necessary transformation. It is necessary, also, to postulate that further transformation is possible, and that the proportionality constant is a function of the external fluid velocity such that /3 = 1 when Um ' = 0. By analyzing the data reported in Ref. 9 we obtain 0 = 1 + Q.2(Um/Ui). Combining this result with Boynton's correlation we obtain an empirical result with good approximation.
