The aim of this work concerns the study of the silicone carbide fluidized bed in order to release a fluidized bed solar
receiver with direct absorption of the concentrated solar radiation and to optimize the quantity of collected energy. For
that, we tested several geometries in order to optimise the distribution of the particles during fluidization. For that, we
built and tested several transparent columns with different geometries and dimensions and analyse several cold
experiments. An analysis of test results and images enabled us to determine the height and the porosity of different layers
in the fluidized bed, to optimise the geometry of the column and its dimensions.
