Optimum conditions of turbulence reduction with screens

The results of an experimental investigation of the conditions of flow turbulence suppression with a set of screens, each of which operates in the optimum regime, are presented. Recommendations are made concerning the choice of the number of screens in the set, their geometric parameters and their location in the flow which guarantee the most efficient reduction of free-stream turbulence.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No.1, pp. 181–191, January–February, 1993.
