turbulent friction velocity 中文意思是什麼
turbulent friction velocity
解釋
亂流摩擦速度-
In this paper, based on summarizing previous numerical studies on wave transformations, several works are documented : based on the mass conservation equation and euler ' s equation, the extended form of boussinesq equations is derived by using the velocity at an arbitrary water depth as the independent variable, and several terms are added into governing equations to model the effects of bottom friction, wave breaking and subgrid turbulent mixing
本文在總結概述前人關于boussinesq方程波浪數學模型研究進展的基礎上，主要做了以下幾點工作：從質量守恆方程和euler方程出發，以某一水層處水平速度矢量作為獨立變量，推導出包含底摩擦耗能、波浪破碎效應和子網格湍流效應的改進型boussinesq方程。 -
Based on the measured data, the change of the friction velocity of turbulent flow and the characteristics of the wall shear stress under different sudden roughnesses and different water depths are analyzed herein
