浅海风生流场控制方程中一般都忽略侧向摩擦项,即不考虑沿岸边界层。本文对其影响作了探讨。通过对几个例子的渐近分析,认为在沿岸水浅时,忽略沿岸边界层是有效的,但是在沿岸水深相当深而水深变化区又足够窄时,忽略沿岸边界层会导致风生流场解的根本改变。 In the shallow sea wind flow field governing equations, the lateral friction term is generally neglected, that is, the coastal boundary layer is not considered. This article discusses its impact. By the asymptotic analysis of several examples, it is considered that it is effective to ignore the coastal boundary layer when the coastal water is shallow, but ignoring the coastal boundary layer will lead to the wind-induced flow field when the water depth of the coast is quite deep and the variation of the water depth is narrow enough The fundamental change of solution.
