Application of innovative physical models for the solution of technological engineering problems

Статья в сборнике трудов конференции

The most important trend in engineering education is the use of advanced physical models to solve technological problems. We present two examples of such an innovative approach. One of the common methods for treating industrial effluents in the coal industry is the use of sedimentation tanks, which are reservoirs into which water is supplied carrying particles of coal and solid rocks. The paper considers the movement of a two-phase medium under the action of gravity with an uneven distribution of the impurity concentration. Under the influence of gravity, a cloud of solid particles sinks to the bottom, and at the same time, due to the difference in concentrations, different parts of this cloud have nonzero velocities relative to each other. Precipitating, the particles engage the carrier medium in motion. As a result, the deposition of groups of particles occurs faster than individual particles. A two-phase convection model is used. In the second example, a method for two-dimensional numerical simulation of submicron field-effect transistors with a Schottky gate is proposed, which allows one to take into account the effects of unsteady electron dynamics and to study complex carrier transport phenomena. The proposed approach allows one to take into account the edge effects at the drain end of the gates, which are manifested in the appearance of regions of high concentration of electric field strength, which significantly affect the nature of the motion of charge carriers.
