COMPUTATIONAL FLUID DYNAMICS ANALYSIS OF TESLA CYBERTRUCK'S AERODYNAMIC PERFORMANCE AT VARYING SPEEDS

Background: The Tesla Cybertruck's unconventional angular design has sparked widespread interest and debate regarding its aerodynamic efficiency. Aerodynamics plays a critical role in electric vehicle (EV) performance, influencing range, stability, and energy consumption. Objective: This study employs Computational Fluid Dynamics (CFD) to evaluate the aerodynamic behavior of the Tesla Cybertruck across a range of speeds, aiming to quantify drag forces, pressure distribution, and flow separation patterns. Methods: A detailed 3D model of the Cybertruck was subjected to CFD simulations using ANSYS Fluent at speeds ranging from 30 km/h to 150 km/h. The analysis included calculation of drag coefficients (Cd), visualization of flow fields, and assessment of pressure zones. Turbulence was modeled using the k-ε and SST k-ω models to ensure accuracy across flow regimes. Results: The Cybertruck exhibited a relatively high drag coefficient compared to traditional EV designs, primarily due to its sharp edges and flat surfaces. However, aerodynamic performance remained consistent across moderate speed ranges, with noticeable increases in drag and flow separation at higher velocities. Conclusion: While the Cybertruck's geometry poses aerodynamic challenges, its performance is sufficient for practical applications. Design modifications such as rear tapering or underbody streamlining could further enhance efficiency without compromising aesthetics or structural integrity.
