| 摘 要： | 采用新的无量纲变量组合推导出波浪破碎形成的气泡总数与气体体积卷入率、湍流能谱密度以及表面张力之间的关系;利用观测结果提出两点假设,并据此将泡径谱N(a)推广为随泡径和深度的分布函数N(a,z)。

| Abstract: | In this paper,new non-dimensional variable combinations are used to derive a relational experssion of wave breaking entrained bubble population to air volume entrainment rate,turbulent kinetic energy spectral density and surface tension;two assumptions are proposed by using the observed results,and the bubble size spectrum N(a) is then generalized to be the distribution function N(a,z) of bubble size and water depth. |
