Significant Research Results for 1971, High Temperature Institute, USSR Academy of Sciences.
Abstract
The Institute's work continued in 4 basic directions in 1971: (a) study of thermophysical and electrophysical properties of substances at high temperatures; (b) study of high-temperature heat and mass transfer and gas dynamics processes; (c) development and study of new heat-resistant structural materials; and (d) research toward development of direct conversion of heat into electricity using MHD generators and other new types of energy units. Properties of plasmas, especially of cesium plasmas, at high temperatures (p = 500 atm, t = 5000K and higher) were studied. Measurements made by the electrical 'explosion' method were made on Fe, Ni, W, Mo and various transition group metals (entropy, enthalpy, heats of fusion, for example). Experimental and theoretical determination of phase diagrams, of e.g. Li-LiH-H2 systems, were prepared, especially at high temperatures and low pressures. Heat and mass transfer and gas dynamics properties of high-temperature heat transfer agents was emphasized. ZrO2-Y2O3-CeO2 based electrodes, as well as LaCrO2-Cr, cermetselectrodes, and high-alumina MgO base cements for insulating materials were studied for MHD applications. The U-25 MHD (magnetohydrodynamics) unit was started up and successfully run in 1971. Power of 75 kW was achieved in MHD generator tests. Various MHD channel configurations were tested extensively. Theoretical studies on the most efficient uses of MHD generators in an electrical power network were made, especially as to their use to carry peak loads on a system.
