Abstract

Engineering method of calculation of one-dimensional double-speed flow of gas suspended   matter in the nozzles of gunned lance was developed. The solution of set of differential and   algebraic equations enabled to calculate the change of static pressure, velocity of carrier gas   and powder, volume fraction of hard phase along the cylindrical nozzle as well as distribution   of these parameters in the outlet section.
