Natural convection heat transfer is a buoyancy-driven phenomenon in which density differences are caused by temperature. Horizontal convection is one of the heat transfer phenomena. In this study, we analyzed numerical and experimental images of the flow field and frequency analysis of temperature and velocity in order to evaluate temperature and velocity transitions in detail when the Rayleigh number is varied while maintaining the aspect ratio of a rectangular model. From the results, changes in the spatial structure of heat transfer coefficient and velocity fluctuations are discussed.
