INVESTIGATION OF CONTROL PROCEDURES OF GAS-DISPERSION PROCESSES IN NON-DESIGN JETS

The aim is to study the control procedures of the processes in such jets for obtaining dispersion composition parameters of the particles and deposition parameters of the particles on the substrate. The algorithm for multiprocessor design of the two-dimensional gas-dispersion supersonic flow with local sub-sonic zones with use of the processor i860 has been developed. The dependences of influencing initial parameters of the gas-dispersion jet on the flow structure in the range of the Mach number from 1.8 to 3 and non-designability rate from 0.5 to 4 have been obtained. It has been shown that there is the minimum of the power costs for achieving the required flow-around conditions of the blunt body. The methods for experimental study on the jet flow-around of the blunt bodies have been developed, the results of influencing recoil of the particles on the distribution of the particles according to the sizes before face of the flow-arrounded body have been obtained. The dependences of influencing of the jet parameters and solution concentration on the size and concentration of the aerosols of the ultra-dispersion particles manufactured by means of the pulverization of the salt solutions have been obtained. The control efficiency of the processed in the gasodynamic technological plants for jet deposition of the fine-dispersion powders has been increased.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
