Trial Manufacture of a Fluctuating Wind Direction Tunnel Using Control of Pressure Slope Direction

Abstract

A newly designed wind tunnel that can fluctuate the wind direction was manufactured on an experimental basis. The tunnel utilizes the control of pressure slope direction. The open and close of the shutters at the inflow and outflow ducts are manually operated, and that resulted in the wind speed fluctuation at the same time of the wind direction change; but wind direction could be changed as planned in general.
