Description
Summary:An experimental rig has been set up to study the processes taking place in the duct of an open-cycle MHD generator. The installation consists of a combustion chamber unit in which natural gas is oxidized in an air atmosphere enriched in oxygen (up to pure O2) with ionizing seeds of different types. The pressure in the duct can go up to 50 atm and the temperature to 3500K. As the combustion products pass into the duct, the nozzle system can vary the Mach number from subsonic to Mach 3. The duct has a rectangular section. Its maximum dimensions, determined by the magnet bore, are 0.2 x 0.34 x 2.5 m. The ducts are interchangeable to give the possibility of varying the area modification law relating to the section along the axis of the duct and of altering the electrode circuit or the size of the electrodes or insulation gaps, etc. The combustion chamber, nozzle and duct are made of stainless steel and are water-cooled; a coating of aluminum oxide serves as insulation. Depending on the mode of operation, the installation's calculated power and electric power are in the neighborhood of 250 MW and 10 MW, respectively. Edited machine trans. of mono.
