  • The Horizontal Wind Tunnel at East London College

  • The horizontal wind tunnel at East London College consists of a wooden tube, .2 feet square in section by lift. 6in. long, through which air may be drawn at velocities up to 50 m.p.h. by means of a 6½ h.p. motor.

    It was designed and constructed by Messrs. Cedric Lee and G. Tilghman Richards from sketches supplied by one of the authors and was modified later by the addition of a wind disperser as the result of information kindly supplied by Dr. Stanton, of the National Physical Laboratory. This disperser was added principally with the object of reducing the draught in the room and of preventing pulsations of the air current.

    The tunnel is provided with a bell mouth to ease the air into it, and at the other end it is connected to the disperser by a metal duct, 3ft. 6in. long, expanding from 2ft. square to 3ft. 6in. diameter. The propeller is mounted in the enlarged end, which is cylindrical for some 7 inches, so as to draw the air through the tunnel.
