Ефективність конічних місцевих смоків із вставками – екранами

Abstract

Attention is paid to the problem of pure air supply. The data of the local suckings of different shapes for isothermal condition are analyzed. The results of experimental investigations are layed – out. The calculations of the changes in axial relative velocities of currents, depending on the distance to suckings, when entering into them are made. A number of methods for the perfection of local suckings designs are suggested.
