Simulation of air distribution rate in the evaporator compartment of refrigerating unit of refrigerating container

The results of the study relate to the refrigeration unit of refrigerating containers and are aimed at solving the calculating the problem of the air rate field at the outlet of the tubular evaporator with tube axial fan in the metal enclosure. Formulation of the problem and its simulation have been performed for two-dimensional coordinate system, and for its solution software environment COMSOL Multiphysics, Femlab 3.0, Fluid Dynamics - Incompressible Navier-Stokes has been applied. The obtained results allow to establish boundary conditions at solving the calculating problem of the air rates field inside the refrigerating container space, and on its basis, the calculation of temperature field distribution.
