An experimental investigation of a simplified full scale underhood engine compartment was conducted under steady state and transient operating conditions to obtain details of air flow and thermal behavior. A simplified full scale engine compartment which has openings to the surrounding environment was used during the phase of the study. The engine compartment had four openings, of which two resemble the vents for the radiator and firewall and the other two slots resembles the gap between the engine hood and the fender. A technique named Particle Image Velocimetry (PIV) was used to obtain the magnitudes of flow velocity components. Temperature values of the engine block and the enclosure were measured using thermocouples. A previous study conducted under the hood of engine compartment only consists of closed enclosure. Therefore, the study of underhood engine compartment with openings will provide a better understanding of the physical phenomena involved to the automotive industry.
