Examples
- This paper has established a class of mathematics model about prandtl boundary layer problem . compare to navier - stokes equation , prandtl boundary layer equation has important simplicity and easier
普朗特边界层方程和纳维? ?斯托克斯方程相比,有了重大的简化。 - In this paper i has applied inverse operator method to the solution of the nonlinear boundary layer equation on base of the former knowledge , and have gotten the approximate analytic solution
本文把逆算符方法应用到了普朗特边界层方程上来,并且求出了逼近解析解。 - Actually , n - s equation has three unknown functions u , v , p and three equations , now prandtl boundary layer equation has two unknown functions w , vand two equations only , and viscosity terms has partly reduced
原来有三个未知函u , v , p及三个方程,现在只有两个未知函数u , v及两个方程,且粘性项也少了一些,这些都是简化的地方。 - The creative points of the thesis are as follows : ( 1 ) the thesis establishes turbulence boundary layer equation that contains centrifugal force in flow field of two - dimension boundary layer of centrifugal pump and gives its solution
本文创新之处是: ( 1 )在离心泵叶轮二维边界层流场内,建立了包含离心力的湍流边界层方程并给出了近似解。 - But on the other hand , should also see , boundary layer equation as before is a nonlinear differential equation set of two steps , the nonlinear nature of equation is still retained , so solving this system of equations on mathematics untie is fairly difficult
但另一方面也应看到,边界层方程依旧是一个二阶的非线性偏微分方程组,方程的非线性的性质仍然保留,这使得在数学上求它的解还是相当困难的。
