摘要
对目前广泛应用于乳化炸药混装车上的水环输送乳胶基质的减阻机理进行了理论分析,分别推导出层流同心水环、湍流同心水环的速度分布与流量计算公式,并得到了从层流到湍流的转捩判据。此外,优化了水环润滑装置结构参数,提出了稳定水环输送的相关措施。
The mechanism of drag reduction by core-annular flow in transportation of emulsion matrix was widely used in the existing mixing-loading truck for emulsion explosive.After theoretical analysis,formulas were deduced respectively to calculate the velocity distribution,flow rate of annular water flow in laminar and turbulent flows.The criterion of transition from laminar flow to turbulent flow was obtained.Furthermore,the optimized parameters and some stabilizing measures are also proposed for core-annular flow device.
