On the Theory of Electrical Phenomena in Combustion of Heterogeneous Systems with Condensed Products

The effect of the electromotive force arising in combustion of heterogeneous systems with condensed products is explained. A convective mechanism of arising regions with different charge densities due to charge transfer by the gas filtered in the pores is formulated on the basis of the developed physical concepts, estimates, and analysis of experimental data. Key words: combustion, electron emission, filtration, electromotive force.     

Interaction Between a Drying Agent and Particles Dispersed by an Airstream Atomizer Inside a Drying Chamber

Results of an experimental study of the aerodynamics and spray density distribution of a liquid dispersed by an airstream atomizer inside a drying chamber. Velocity components of the drying agent and their radial distributions as a function of the distance from the spray plane are determined. Relationships for the distribution of dispersed liquid inside the drying chamber are derived. Interactions between the drying agent and the product in the drying chamber are analyzed.

Adaptive control of diamond drilling of nonmetallic materials

The basic principles for selecting the work regimes for diamond drilling of nonmetallic materials are presented. The process of microcutting by a single diamond grain is examined, and relations between the components of the cutting force and the ratio of the rate of the main motion to the feed rate are obtained on the basis of known relationships. It is shown that adaptive control of the drilling nonmetallic materials is possible using two-circuit systems — one for feed-rate control and one for cutting-rate. __________ Translated from Steklo i Keramika, No. 3, pp. 28–30, March, 2007.
