Goal
- The aim of the course is to study the kinetic theory, which allows us to obtain formulas for transfer coefficients and fluxes in inhomogeneous media through the parameters of interactions of molecules and microparticles. In the course of studying the discipline "Kinetic theory of thermal engineering phenomena", examples of specific application of statistical methods of description to inhomogeneous gases are revealed, a physical approach to solving problems is formed, based on the opening of the mechanism at the molecular level. For practice, the kinetic theory makes it possible to calculate the thermophysical parameters-the coefficients of viscosity, thermal conductivity, diffusion according to the formulas obtained by molecular-kinetic representations, based on molecular-kinetic representations.
Objective
- As a result of studying the discipline "Kinetic Theory", the master student must form the phenomena of thermal engineering concepts: about the basic concepts of the elementary kinetic theory of thermal phenomena; about the basic concepts of a rigorous kinetic theory of thermal phenomena; on the molecular-kinetic nature of the phenomena underlying the processes associated with heat and mass transfer; on modern schemes for describing computational models for determining the real properties of substances.

Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
