A new concept of fluidized bed will be shown which can be used for various gas-tosolids reactions (e.g. chemical vapour deposition (CVD) reactions) with high throughput like the production of new materials. For the design and scale-up of the new bubbling fluidized bed with vertically aligned vertical nozzles the fluid dynamics of the fluidized beds have to be determined and analysed, especially the flow around the gas nozzles. A jet region around a single centrally arranged injector lance in a bubbling fluidized bed reactor is characterized by different parameters like solids concentration and jet gas distribution. It can be shown that – depending on the related parameter – different jet regions are obtained.
