PRACTICAL FORMULA FOR EFFECTIVE HEIGHT OF IMPERMEABLE HANGING CURTAIN IN STEADY WATER FLOW

Abstract

 This study aims to propose a new prediction formula of the effective height of a hanging curtain in steady water flow. According to the hydraulic experiments and numerical calculations, the more practical calculation formula of the effective curtain height was obtained using the ratio of dynamic pressure and weight and the ratio of the effective curtain height to the curtain length. Our formula is characterized in that the experimental coefficient is without user specification, and the weight is included in the formula, and the parameter using the ratio of the initial curtain height to the water depth is used.
