Research Methodology for Microwave-Convective Processing of Grain

Studying the effect of microwave fields on the intensification of heat and moisture exchange processes in a granular layer is a rather complicated task, which cannot be effectively solved without an adequate research methodology. In presented materials, a system of principles and approaches for studying processes of microwave-convective grain treatment has been discussed. Based on the explicitly defined process target, functional-physical analysis has been performed that made it possible to specify the most essential factors of process. Morphological analysis of processes shall be performed in several stages. At each stage, targets of process have to be set by excluding combinations of factors that have no reason to be considered at this particular stage of process development. Application of mathematical simulation methods is advisable for selection of optimal options.

Mathematical Simulation Methods to Evaluate the Effects of Actions on Conditional Preventive Maintenance of Complex Systems

In this work, we propose two mathematical simulation methods to evaluate the results of conditional preventive maintenance strategies based on controls and inspections with optimal performance. In order to have an optimal availability of the equipment in question, the evaluation of the maintenance strategies associated with the controls will be treated by the method of the fault trees based on the decision binary diagram with the calculation engine ALBIZIA. The maintenance performance associated with inspections will be determined by Petri networks coupled with the Monte Carlo method.

Mathematical Simulation the Influence of Tundish with a Retaining Wall

Placement in the middle retaining wall package, aimed at controlling the flow of liquid steel forms, so that movement of a reasonable level remained stable, while reducing interference from turbulence and dead zones, molten steel in order to extend the average stay of removal in favor of inclusion to improve the cleanliness of molten steel.In this paper, with the tundish wall flow field of research is the use of mathematical simulation methods, three dimensional mathematical models are currently being used successfully to simulate liquid steel flow and temperature distribution, the large-scale universal Finite Element analyses software ANSYS CFX is used and many models based on different tundishes are built
