Abstract:
Inhencemant of automobile radiator heat performance is the purpose of this study. Radiator fin shape, coolant fluid properties and influence of nanofluid studied in this research. Plain fin, louvered fin and vortex generator fin is choosen and design. With flow simulation influence of fin shape on heat performance is studied. After that, with considering radiator coolant fluid, the effect of antifreezing on fin heat transfer is evaluated. Then by addin nanoparticles to water and antifreezing solution, effect of nanofluid on heat transfer is evaluated. Results show that with increasing the air velocity for all geometries in the study , heat transfer and pressure drop is increased. But heat prerformence decreased. Between these geometries, louvered fin has the most heat transfer(20 percent more than plain fin). By increasing the volume percent of antifreezing the heat transfer is decreased. But adding aluminuim nanoparticles and copper nanoparticles improve heat transfer and become better than pure water
