计算明渠非恒定流的一个Lattice BGK模型
A Lattice BGK Model for Simulating One-Dimensional Unsteady Open Channel Flows
摘要
Abstract
A lattice BGK model for one-dimensional unsteady open channel flows is established by analyzing the multi-scale equations of the LB method and St. Venant equations. Some classical and practical flows, such as unsteady open channel flows in headraces of hydropower plants and dam break waves, are simulated by the LB scheme. The LB results are in good agreement with the results of implicit Preissmann scheme and the method of characteristics. It is shown that the LB method is a feasible and accurate approach to simulate one-dimensional unsteady open channel flows in engineering.关键词
