概要

Flow and temperature distributions were measured for natural convection in a rectangular enclosure filled with water. To express a scale model of a residential room with a floor heating system, one of the vertical walls of the test space was cooled to keep the surface temperature almost constant and the bottom wall surface was uniformly heated. Experiments were performed at the Rayleigh number 1.9x10^<10> 〜 3.8x10^<10>. PTV(Particle Tracking Velocimetry) method was applied to measure very slow flow fields, and thermocouple device was employed for temperature field measurements. At near wall regions, detailed data were obtained mainly in a center vertical plane under several heating conditions. These data are arranged to validate numerical methods for the prediction of thermal environments in floor heating rooms.
