概要	Extensive parametric studies are made of flow and heat transfer of a viscous fluid contained in a square cavity. Flow is generated by the top horizontal boundary wall, which slides in its own plane at constant speed. A stabilizing externally-applied vertical temperature gradient is imposed on the system boundaries; the top wall is maintained at a higher temperature than the botom wall. Numerical solutions to the Navier-Stokes equations are secured over broad ranges of the parameters, 0 < Ra < 10^6, 0 «$ Re < 3000, Pr ~ 0(1), aspect ratio ~0(1). Systematical evaluations of the numerical results are carried out to ascertain the relative importance of natural and forced convections. Representative plots illustratingthe velocity and thermal fields are presented. These clearly identify the major dynamical ements in various regimes ofthe parameter spaces.
