Approximate probability distribution for peak pressure coefficients on circular cylinder

Abstract

The characteristics of the fluctuating external wind pressures on circular cylinder have been investigated based on the data obtained from a series of wind-tunnel measurements in simulated atmospheric boundary layers. Focus is on peak pressure coefficients of probability density function. A model of the peak factor on the circular cylinder is proposed as a function of the values of skewness and kurtosis. This model is first step for approximating the fluctuating wind pressures.
