Paper Abstract

A small rotating disk generator, particularly suited for closed cycle operation has been built and operated successfully. The generator has no external drive for the disks, but is rather driven by the momentum of the injected basic hydrogen peroxide. The rotation rate and the submergence of the disks in the liquid pool can be adjusted independently by the liquid flow rate, the size of the injection nozzle, the height of the outlet for the liquid, and also by the amount of injected gas. The closed cycle comprises a liquid reservoir for the cooling of the liquid and for the sedimentation of crystallized salt, and a gear pump for circulation of the liquid. First results for utilization and yield have been gained as a function of total pressure, rotation rate, and gas flow rate and composition. The performance of the generator shows a remarkable improvement over a Sparger type generator for equal flow rates.
