The study was conducted primarily to obtain a method of determining a formula that could be used to approximate the discharge through channels formed by a selected range of applications of nuclear explosives. The study included tests of three small scale channel sections, one channel with straight smooth sides, and two channels with selected forms of expanding and contracting sections throughout the length of each channel. Concurrently an analysis of isostatic losses was conducted to allow the development of a general equation that could be used for channels with significant expansions and contractions. An equation applicable to the specific range of expansions and contractions subjected to model tests is developed, using the results of the hydraulic model tests. General information on velocity distribution within the channels is presented. The data showed that flow separation occurs at each significant area of contraction with resulting modification of the flow distribution downstream from the expanding area. Author
