Unsteady natural convection of an initially isothermal fluid in a square enclosure is considered by experimental and numerical analysis. The enclosure is composed of hot and cold vertical walls and confined by two horizontal adiabatic walls.
The horizontal and vertical components of velocities are measured by laser speckle photography for the Rayleigh numbers of order 10^6-10^7. In the laser speckle photography both the whole field and pointwise reading method are used. The numerical study is, also, performed for the same order of Rayleigh numbers on the assumption of two dimensional flow. The convection term is discretized by using two dimensional QUICK (Quadratic Upstream Interpolation for Convective Kinematics) scheme and SIMPLE algorithm is adopted for the calculation.
