Although the effect of radiant heat transfer is important for the natural convection field in large-scale systems, the influence of the radiation on the natural convection has not yet been clarified experimentally. This study is focusing to evaluate the mechanism of the effect of radiation on the convection field from the viewpoint of experimental and numerical analysis. In order to achieve the purpose, the Mach-Zehnder optical interferometer is used in this study to change the emissivity of the wall surface inside the rectangular cavity. Visualization measurement of changes in the natural convection boundary layer under the influence of radiation caused by this is performed.
