dc.description.abstract NOAH car is a four wheeler minivan or passenger car which is a popular means of transportation in Bangladesh due to its comfortability, provision to go anywhere like for any occasion, family program and official use. But the aerodynamic drag has a great contribution on its energy and fuel consumption which is 0.4001 for the base model. In our investigation we used ANSYS Fluent software with CFD simulations for add-on devices. We used contour bump on the rear roof of the existing model without changing its external and internal design. The 3D designs of solid model are taken into account for the simulation of flow visualization around the car. Coefficient of drag CD was found numerically for all the models where we got 0.3859 for using one bump which reduce the drag by 3.5% and the maximum reduction was 0.3843 by 3.95% for two bumps configuration. Other six configurations are also effective but less efficient than the two proposed model of one and two bump configurations. Also the fuel consumption was reduced by maximum of 2.37% for two bump and 2.1% for one bump configuration. Also we have got an effective result for stream wise configuration of two bumps where we got maximum drag reduction of 3.85% which reduce the fuel consumption by 2.31%. en_US
