Corroboration of the new method of obtaining dissipation in wake flow
Abstract
A two-dimensional far wake of a circular cylinder is investigated for the average turbulent kinetic energy equation. The dissipation term is obtained from the average u sq spectra using a new method, called the zero-length method. This method has previously been tested successfully in boundary-layer flow, fully developed pipe flow, and diffuser flow. The dissipation obtained through this method in the present study compares very well with the best values of dissipation available up to date in a similar flow. Additionally, the results of dissipation satisfy the closing term of the energy equation. It seems that this method of measurement of dissipation is universal in nature.
