Plane-Parallel Nonisothermal Gas Filtration: The Role of Thermodynamics

摘要

The influence of the mathematical model parameters and the type of boundary condition on the dynamics of temperature and pressure fields in non-isothermal gas filtration is studied in a computational experiment. The process is described by a nonlinear system of partial differential equations, which is derived from the laws of mass and energy conservation, and the Darcy law, the closure relationships are physical and caloric equations of state. The boundary conditions correspond to gas injection for the given mass flow rate with varying intensity.
