Abstract
Simultaneous quantitative measurements are made of both the temperatur e and velocity fields for two-dimensional transient natural convection in an inclined rectangular enclosure using calibrated multichannel el ectronic interferometry and digital particle image velocimetry. The tr ansient boundary conditions are initiated impulsively by heating and c ooling two opposing walls. The evolution of the flow to steady-state i s determined for a Prandtl number of 6.38, a Rayleigh number of 1.5 x 10(5) and an aspect ratio of 1.0, at angles of inclination of pi/4, pi /2 and 3 pi/4.
