An approach for predicting the spatial variation of the energy dissipation rate downstream of a screen is proposed in this article. It is based on extending the use of the homogeneous and isotropic turbulence decay equation to the very thin anisotropic region adjacent to the screen. Whereas the decay exponent and origin were kept constant in conformity with other previous investigations, the decay coefficient was slightly altered. This approach was found to be capable of predicting the experimental energy dissipation data obtained using liquid flow through screens and screen-type static mixers reasonably well over a wide range of design and operating conditions.
