- Аннотация: Results are given of experimental and numerical investigations of electrical conductivity and mobility of electrons in the products of combustion of hydrogen-oxygen fuel seeded with cesium or potassium-sodium eutectic. The experiments were performed in model (flow rate of 0.9 kg/s, thermal power N-th approximate to 7 MW) and large-scale experimental (flow rate approximate to 12 kg/s, N-th approximate to 150 MW) facilities with the pressure in the combustor ranging from 2 to 6 MPa, oxidizer excess coefficients of 0.6 to 1.1, mass fractions of the seed in the fuel of 0.3 to 0.9 with the Mach number M approximate to 2.4. The basic characteristics, structural schemes, and general views of the facilities are given. When cesium is used for seeding, the experimentally obtained values of electrical conductivity may be as high as sigma(el) approximate to 20 S/m, those of sigma(el)nu(2) approximate to 115 S/m (km/s)(2), and of electron mobility - 0.11 T-1 at a pressure of approximate to 0.3 MPa, temperature of approximate to 2800 K, and flow velocity nu approximate to 2500 m/s. Under the same conditions for combustion products seeded with KNa eutectic, we have sigma(el) approximate to 9 S/m, sigma(el)nu(2) approximate to 65 (S/m)(km/s)(2), and electron mobility of 0.09 T-1.
