Abstract
The natural convection in a reservoir sidearm induced by solar radiation is visualised using a shadowgraph technique. The flow visualisation reveals three stages of the flow development, namely an initial growth stage, a transitional stage and a quasi-steady stage. At the initial growth stage, a distinct thermal boundary layer grows rapidly along the sloping bottom. The transitional stage is characterised by the onset of convective instability in a form of rising plumes. At the quasi-steady state, the mean temperature across the enclosure increases steadily in time and the flow is sighted with quasi-regular presence of instabilities with reduced intensities.
