Abstract:

The main objective is to enhance the thermal comfort by modifying the HVAC ducts inside a Multi Utility Vehicle (MUV) cabin. A modified Duct is presently established in a Sedan, a four/five seated vehicle. The study relates with a motive for utilizing the same duct for a (MUV) in this case a seven seated arrangement. Since the air flow is hard to model mathematically, multiphase flow analysis is to be carried out by means of CFD software. The interior of the cabin is designed using a CAD software and enables to easily understand the flow procedure within the duct and responsive to flow velocities inside the cabin. The flow parameter involves the selection of appropriate duct model for the prediction. The model of a car is made by SOLIDWORKS software. The airflow velocity and directivity due to the modification in ducts is analysed with the ANSYS fluent software.
