| Research Abstract |
Onset of thermal convection of a fluid in a rectangular horizontal or inclined container is examined. Here all the walls of container are of perfect thermal conductance, and external temperature field is linearly decreasing upward. By a numerical analysis, the dependences of critical Rayleigh number Rc and the flow structure of most unstable mode on the aspect ratios and inclination angles of container are clarified. Moreover, the characteristics of trajectories of fluid particles in the velocity field of most unstable mode are clarified.
