Optimization of the air distribution system in motor vehicle cabin using computational fluid dynamics

The paper presents the application of CFD software for simulating the conditions that prevail inside the air distributor of the vehicle's ventilation system with the aim of increasing the efficiency of the distributor. The simulation results were validated based on the experimental data found in the literature. Based on the results of the simulation, the geometry of the distributor was optimized with the aim of reducing the pressure drop through the ventilation system. It was found that optimizing the distributor geometry to some extent can provide a more energy efficient ventilation system.
