Abstract:

Use of piston-type flow in liquid-metal MHD systems is proposed in order to counteract Rayleigh-Taylor instability. Two main advantages are cited 1 difficulties connected with acceleration are excluded inasmuch as the generating of electrical energy is guaranteed basically because of the gas expansion in the generator duct itself flow rate can be more moderate, impossible in systems with continuous flow and noticeably reduced hydraulic losses 2 in view of the small contact surface between liquid metal and gas and the low coefficient of temperature transfer of gas, a lower temperature of the thermodynamic cycle can be selected independently of the temperature of hardening of the liquid metal, consequently, there appears a possibility of a noticeable increase of the thermal efficiency of the cycle 3 the possibility appears of realizing the powerful effective and technically perfected synchronous principle of conversion of flow kinetic energy into electrical energy. These features show that a liquid-metal MHD system with piston flow and with electrical energy takeoff by the synchronous principle will be high-power. Author
