Martynenko M. Hydrodynamics and heat and mass transfer of chamber type pneumo-pulse apparatus.

The investigation of hydrodynamics, heat and mass transfer of chamber type pneumo-pulse apparatus was carried out. The physical representation of real processes in pneumo-pulse apparatus is offered. The results of modeling of two- and three-dimensional fluid motion are presented. Fields of velocities and stream functions are determined. Peculiarities of hydrodynamics and heat transfer of chamber type pneumo-pulse apparatus are analyzed. Jet velocity in the tube of pneumo-pulse apparatus was experimentally obtained. The computation al relations and experimental data for deflection of rubber membranes in chamber-type pneumo-pulse apparatus are presented.. The improvement suggestion of camber design and mode of operation of pneumo-pulse apparatus are offered. The economical efficiency and power-saving effects at liquid extract processing are analyzed.
