Electric characteristics of a high-frequency torch discharge measured by the resonance method are presented. It is shown that discharge capacity determined by the modified Neumann scheme is close to the value of electrostatic capacity. Capacity of discharge channel was calculated with...
Abstract The role of electromagnetic forces and the forces of viscous friction with the arc plasma flow in the flow formation within the cathode melt is considered within the framework of numerical modelling; a comparative estimation of the separate influence of each of the above forces is...
The spatial combustion of turbulent jets in furnace devices is modelled numerically basing on equations for multi-component turbulent reacting gaseous mixtures. The dependencies are obtained for the influence of the secondary air velocity and composition of gaseous components on torch...
The experimental data obtained previously on the investigation of power characteristics and the possibility of the self-start of the Darrieus rotor are anlysed. These results are used at the design of new two-tier wind turbines with straight blades. The full-scale tests of two design variants...
Operation of the diametrical disc fan was studied experimentally at low (5–50 torr) pressures in air. The effect of a drastic decrease in volumetric flow rate of the fan was revealed at pressures below 40 torr (flow rate crisis), what does not correlate with published data. The critical value of...
