Predicting and improving vehicle passenger compartment ventilation requires a good understanding of the flow velocity distribution in the cowl. In this work, the air flow velocity distribution in a cowl model was determined by measurement of visualized flow and numerical analysis. Flow measurements were obtained using a method which combined particle tracking with a pulse-laser-light-sheet technique. A third-order upwind finite difference method was used in the calculations. A comparison of the visualized and calculated flow distributions indicated that the results were in good general agreement. In addition, using the visualization technique, flow velocity distributions in a passenger compartment were measured when four dummies were placed in the front and rear seats.
