Optimal control of free-stream turbulence intensity by means of honeycombs

The characteristics of honeycombs of different shapes and sizes used for reducing free-stream turbulence in wind tunnels have been experimentally investigated. The optimum geometric dimensions of the honeycomb and its optimum location in the wind tunnel necessary to ensure a minimum level of turbulence in the working section have been determined.Moscow.
