โœฆ Synopsis


In a previous paper under a similar title 3 the author solved the set of five equations of a steady turbulent flow of a compressible fluid in a wake far behind a solid symmetrical body for the assumed condition that the velocity distribution is based on the momentum transfer theory. In the present paper an equal number of equations, based on the vorticity transfer theory, were solved. Comparison and inspection of both solutions shows the largeness of discrepancies between the results based on the two theories. On the basis of performed calculations, the following conclusions can be drawn:

(a). The calculated velocity distributions, based on the two theories, i.e., the momentum transfer and the vorticity transfer theories, are identical only to the approximation of the first order. Beginning from the approximation of the second order there are increasing discrepancies between the results based on both theories. In the approximation of the third order the differences are very significant.

(b). The calculated temperature distributions, based on the two theories, are much different beginning from the approximation of the first order.

(c). The calculated pressure and density distributions, based on the two theories, are different beginning from the first approximation, giving results different from zero, i.e., from the approximation of the second order.
