不同流量下渐扩段局部水头损失数值模拟
Numerical Simulation of Local Head Loss of Gradually Broadened Channel under Different Discharges
摘要
Abstract
The water surface profile of gradually broadened channel is simulated with HD (hydrodynamic) model in MIKE software,and the change rules of water surface profile and flow field of local head loss are obtained.The sim ulation results are compared with results calculated by empirical formula,and the conclusion reveals that the simulated water surface profile of gradually broadened channel agrees well with the calculation result;MIKE could better simulate the local head loss by reducing the difficulty and complexity of formula calculation,hence achieving a precise simulation.关键词
