Abstract

In this study, aerodynamic performance of a solar car (Anadolu Solar Team) is investigated using Computational Fluid Dynamics (CFD). This work represents the current efforts in designing a new vehicle. Aerodynamic concepts were used to modify the previous car, namely the Sunatolia II. A new design is performed by eliminating the aerodynamic efficiency drawbacks of the Sunatolia II. Aerodynamic calculations include two essential force components as drag force and lift force acting on the body (vehicle). The goal is to keep lift force in optimum level and drag at a minimum for safe speeds and with minimum energy consumption. Aerodynamics of five different vehicle geometries is studied (without body accessories/additions, air breather, side bars, back flap, and vehicle with all added). The CFD analyses were performed with proper turbulence closure, mesh independency tests and a transient solution for accuracy. The results represent one of the shortlisted final designs.
