ECOLOGICAL SAFETY PREDICTIVE MODELING CONCERNING FINE COCOA DUST DISPERSION, RELEASED BY CONFECTIONERY MANUFACTURE

In order to predict ecological safety conserning cocoa dust emission (SP2,5 and SP10), the mathematical modeling of its dispersion was performed considering the atmosphere turbulent diffusion. Necessary gravity sedimentation rate of cocoa dust for modeling was identified during the experimental
researches. Obtained results indicate the necessity of intensification of fine particles emission clean-up in the observed confectionery factory.

Evaluation of the mathematical models adequacy of nom-10 voltage transformer for the frequencies of the free component of the power system internal overvoltage

A synthesized mathematical model of a voltage transformer “NOM-10” (Single-phase Oil Transformer-10) was used to get experimental results with quite high level of accuracy, which, however, weren’t used in synthesizing of the model. The mathematical model recreates electromagnetic processes in a “NOM-10” transformer and can be used for further researches
