Note (General): This paper presents a description of the design concept of the regulating valve and perforated-plate type pressure reducer for the NAL high Reynolds number two-dimensional wind tunnel, along with the results of the model tests of the components. The design data was obtained by conducting the tests in simulated tunnel flow using two regulating valve models, with and without diffuser, and various perforated-plate models of differing porosity. The results of the tests are as follows; (1)the diffuser for the axisymmetrical regulating valve effectively extends the duration, (2)an experimental formula for the pressure loss coefficient was obtained as a function of porosity and pressure ratio, (3)acoustic efficiency of the perforated-plate is on the order of 10(exp -5).
