We’ve evaluated the best 7-passenger SUVs in the USA to help you find one that meets your requirements. Also, in terms of spatial discretization, it was used for pressure.The modern 7-seater SUV needs to tick many boxes: it needs to drive well, have seating and room enough for seven occupants, and all the features you need to keep everyone safe and happy. The second-order upwind approach has been used for the momentum, turbulent kinetic energy, and turbulent dissipation rate. To optimize the design and mesh, the underbody surface became flat. The car’s tyres have all been stationary, analogous to the wind tunnel model. As a result, there was no vicious influence on the analyses because the domain’s external walls were identical. Two types of wall boundary conditions for the sidewalls and top wall of the computational domain could have been: (i) non-slip and (ii) stationary walls. The same turbulence intensity is used in all numerical simulations. In the experimental test, turbulence intensity was 2.65% at t the inlet of the MIRA wind tunnel. The inlet velocity of airflow was about 28 m/s at the inlet section of a wind tunnel. The stationary road under the vehicle is used in numerical simulation, as is the experimental test conducted by MIRA wind tunnel. Discovery car and all its tires were stationary inside the MIRA wind tunnel. Experimental tests for the baseline model of the Discovery car were done in a MIRA wind tunnel in the UK 26, 27. Reynolds numbers ( \(Re\)) of the system were 9 × 10 6, 11 × 10 6, and 13 × 10 6 for the aforementioned velocities, respectively. The increase of the flow turbulence in the wake causes \(\). A wagon car can be considered a good example that has a relatively high rake angle ( \(\phi\)), producing the separation before the back windscreen. Furthermore, global warming increases the pressure on designers to make efforts to design vehicles with low drag coefficients using minimal changes in the shape Krishnani et al. They found that this goal can be achieved by reducing the aerodynamic drag hence, the required performance can be optioned with less fuel consumption 8, 9, 10, 11. For that reason, the researchers have done an extensive study to minimize fuel consumption at the same performance. Furthermore, the vehicles have been registered as the major fuel consumers. The global demand for fuel, as well as the environmental issues, push researchers to investigate ways to minimize the consumption of fuel. The hatchback automobile was picked because it is favored by most individuals who value their money 4, 5, 6, 7. Aerodynamic experiments on a hatchback automobile were carried out to improve both characteristics at the same time. Traditional methods of lowering a vehicle’s fuel consumption include reducing its total weight, adjusting the engine volume, the engine combustion process, and so on, all of which directly impact its comfort and performance. As a result, experts are attempting to lower the fuel consumption of road vehicles even a slight reduction will be a significant accomplishment 1, 2, 3. The majority of cars in developing countries are petroleum-powered, and fuel consumption is rising at an alarming rate of 5% per year. At the same time, low fuel usage is critical for emerging countries since it helps with economic growth. In today’s society, road vehicles’ safety, effectiveness, and convenience are critical characteristics.
