Experimental Study on Hydraulic Characteristics of Multi-Strand Elongated Jet Impinging into the Plunge Pool
摘要
Abstract
Without impact happened to the multi-strand elongated jet impinging into plunge pool is attained by applying the flaring piers and slit-type bucket respectively,achieving multi-jet discharged without collision to high arch dissipate energy. However,the effect of the spacing between each strand elongated jet on its energy dissipation needs further study. In this paper,the effect of the lateral spacing between each jet on the hydraulic characteristics in the plunge pool was studied experimentally on the hydraulic model 1:400. The results show that with the lateral spacing of elongated jet reducing,the jet mixes with each other,the pressure peaks form of the impact pressure combines into a single peak and the impact pressure increases. With the upstream water level increasing,the impact pressure increases. While,the deeper the depth of downstream water cushion is,the smaller impact pressure will be.关键词
