Perancangan Dan Analisis Aerodinamika Mobil Prototype Gardapati Menggunakan Metode Computational Fluid Dynamics

---

Aerodynamics is one of the important parts of a vehicle because aerodynamics has a major influence when the vehicle is moving at a certain speed. Aerodynamics is influenced by form factors and fluid flow that is in direct contact with the vehicle surface. Aerodynamic drag is caused by the occurrence of a stagnation area at the front of the vehicle through which the fluid flow passes, the drag that occurs will singnificantly affect the efficiency of fuel consumption. Thus, the purpose of this final project is to design a more aerodynamic prototype car body that has a small drag coefficient and lift coefficient with reference to the Energy Saving Car Contest standards.This final project will be carried out in several stages of research. The first stage is validation of aerodynamic characteristics simulation using ahmed body, then designing several prototype car body designs using inventor software and simulating characteristics using ansys R1 2020 software. At the time of aerodynamic simulation, the speed was varied from 5,55, 8,33 to 8,33 m/s which was adjusted to the needs of the Energy Efficient Car Contest (KMHE) regulations. At the last stage, a decision-making matrix and analysis of the coefficients of drag and coefisient lift were carried out.From the results of the aerodynamic characteristics validation simulation using the ahmed body, it is known that the large % error in the coefficient drag and coefficient lift under 10%, meaning that the simulation results can be accounted for because they have a % error < 10%. The results of the simulation show a decrease in the drag coefficient value of the first candidate body against the Asykar proto body, namely at a speed of 5,55 m/s a decrease in drag coefficient of 40.26% at 8,33 m/s a decrease of 51.73% at 11,11 m/s a decrease of 53.15%. This occurs because of the reduction in the stagnation area on the first candidate body so that the first candidate body can be said to be more aerodynamic.
