Abstract

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.

Research Method

Methodology, in its practical sense, is a system of principles and approaches for research activities that have to be adhered by researchers in the course of obtaining and development of knowledge, in the frames of a specified problem (Novikov & Novikov, 2013; Lukashevich, 2001, Ruzavin, 1975). The following system of principles and operation sequence was applied in the course of studying the process of microwave-convective treatment of grain:

  • 1.

    Development of process block diagram;

  • 2.

    Development of the target statement for technological process;

  • 3.

    Defining controlled parameters, control actions, initial conditions and status options for the object under control;

  • 4.

    Application of functional-physical analysis to controlled parameters, control actions, initial conditions and status options of the controlled object;

  • 5.

    Morphological analysis of the process under development and selection of appropriate variants of initial conditions, controlled parameters and control actions. Adjusting the purpose of the process;

  • 6.

    Development of mathematical model for the process under study:

    • a.

      Description of dynamic properties of the subject of research;

    • b.

      Specifying initial and boundary conditions;

  • 11.

    Planning of experimental studies designed to check validity of model-based analysis results;

  • 12.

    Development of experimental equipment and carrying out experimental studies;

  • 13.

    Experimental results analysis;
