Abstract
The results of the simulation of car radiator operation with a large range of changes in the volume flow rate of liquid inside the tubes were presented. The change of the flow regime from laminar through transitional to turbulent flow was taken into account. Semi-empirical and empirical relationships for the Nusselt number on the liquid-side in the laminar, transitional, and turbulent range were used. The Nusselt number on the air side was determined using empirical power-type correlation. The friction factor in the transition flow range was calculated by linear interpolation between the values of the friction factor for the Reynolds number equal to 2100 and 3000. The water and air temperature at the outlet of the heat exchanger were calculated using effectiveness-number of transfer units method. The heat-flow rate from water to air was calculated as a function of the water-flow rate to compare it with the experimental results. The calculation results agreed very well with the results of the measurements.
