【摘要】 考虑底部温度高于顶部温度的两平行板间流层的Benard对流问题,该问题可以用Navier-Stokes方程与热传导方程来描述,对其速度场和温度场等相关变量进行二维傅立叶展开,经过复杂运算得到几个新五模类Lorenz方程组,对这些方程组的动力学行为进行了数值模拟.更多还原

【Abstract】 Benard convection problem with different bottom and top temperatures,by Navier-Stokes and heat conduction equations.Several five-mode Lorenz equations are obtained using Fourier series for the fluid velocity and the temperature fields.Dynamical behaviors are simulated numerically by computer according to the changing of Rayleigh number.更多还原
