Numerical simulation of the velocity and temperature distribution in a finned heat exchanger was performed. The simulation was carried out by taking into account the temperature dependence of physical properties of air. In order to observe a velocity field, visualization experiments on flow through large-scale models of a louvered fin array were conducted using hydrogen-bubble and dye injection techniques. We found a good agreement between the numerical simulation and the flow visualization. We also note that an appreciable difference in the average Nusselt number for a parallel louvered fin has been found between the numerical simulation which includes the temperature dependence of physical properties and the same simulation without temperature dependence.
