Abstract

The paper reports on an experimental and analytical investigation of temperature structure in a shallow layer of water heated by an external radiation source. Experiments have been performed in a test cell of known bottom reflection characteristics and suitable for optical observations. Experimental results obtained show that absorption of radiant energy by the substrate and/or by the water near the bottom results in an unstable situation and that natural convection flow develops. However, with continued heating the flow is suppressed. Analytical results, supported by the data, indicate that the spectral radiation flux incident on the water surface, the spectral radiation characteristics of the bottom, and the depth of the water have a decisive influence on the temperature distribution.
