dc.description.abstract | An improper air distribution within refrigerated truck chambers is the major cause of inadequate road transport of perishable products under controlled temperature. Inadequate temperature control permits microbial and/or enzymatic deterioration. Experimental results in refrigerated long road vehicles show temperatures differences in the cargo of as much as 12ºC. This paper presents a computational model to predict, and visualize, the temperature conditions (e.g. velocity, temperature and relative humidity) in refrigerated truck chambers. The model consists of a computer procedure, in which the general equations describing the airflow pattern and the heat/mass transfer in a refrigerated room are solved using the finite volume method. The effect of turbulence is described by the k-ε turbulence model. The computer model was experimental validated by measurements taken from a reduced-scale model designed to provide similarity with a prototype. The model was applied to calculate the indoor cold conditions provided by different types of air supply systems used in compartments of long road vehicles. | por |
