Wind pressure distributions on a 3-dimensional prism model in natural wind

Abstract

Wind pressures on a 3-dimensional prism in natural wind were measured with 180 manometers. Displacement of meniscus in each manometer was reduced to wind pressure data through a new measurement system, which the authors developed using VTR and an image processor. The contours of wind pressure distributions on a prism model at every moment were drawn with this system.
It has been found that local severe suctions on the side of the prism model were caused by the two types of conical vortices showed in wind tunnel tests.
