【Abstract】 The Benard convection problem with different temperature between bottom and top is studied,It is described by Navier—Stokes equation and heat conduction equation.For the fluid velocity field and the temperature field,using Fourier series we obtain several five—modes Lorenz equations.The chaos behaviors are simulated numerically by computer according to the changing of Rayleigh number.更多还原
