Résumé

Materials of the study are directed on the solving the problem of air velocity calculating in a confined volume of refrigerating chamber of 20 foot refrigerated container with forced air convection from Carrier Transicold producer firm and on this basis of convective heat transfer. Problem simulation has been performed in a two-dimensional coordinate system using COMSOL Multiphysics, Femlab 3.0, Fluid Dynamics - Incompressible Navier-Stokes - Convection and Conduction software. As an object of research differential equations of air movement impulse and transfer of energy with it were applied. As a subject of research was selected thermal physical phenomena inside and around the net volume of empty and loaded refrigerated container at air movement. Significant impact of the air movement on the temperature distribution inside the refrigerating container chamber has been established. The obtained results allow to get closer to the theoretical evaluation of the refrigerating machine efficiency in an ordered mode during changes of thermophysical parameters of cargo volume and the environment during perishable products transportation. Tested method is useful for application by scientists and post-graduate students engaged in theoretical simulation of heat transfer problems in the field of refrigeration engineering.
