Abstract

619,250. Wind tunnels. MURRAY, F. R. Nov. 27, 1946, No. 35229. [Class 4] Apparatus for studying the effect of pressure gradient on fluid flow at a fluid-solid boundary comprises a closed channel, means to induce a flow of fluid therethrough and means to modify the flow conditions in the channel by inducing fluid flow through a permeable portion of the channel wall. In the form shown, the apparatus consists of a wind tunnel of rectangular section, one wall 13 of which forms the test wall and is provided with static-pressure heads 14 and traversing pitot heads 15, 16, the opposite wall having an air-permeable portion 18 in communication with a branch channel 20. Flow through the main and branch channels is controlled by blowers 12, 21 and flap valves 22. The permeable portion 18 of the channel wall may be formed from fin-and-tube radiator matrix, or by a honeycomb structure which may be used to support wire gauze. The apparatus may be employed in connection with diffuser design, airflow in engine duct entries, or boundary-layer flow conditions over aerofoils, the test wall of the channel being shaped to correspond with that of the surface to be investigated.
