Paper Title
Influence of the Urban Solar Car Velocity on the Drag Coefficient

Abstract
The purpose of theresearch is to analyse the aerodynamic properties of solar car Eagle Two for the sake of solar car competitions. The article focuses on the determination of drag force and drag coefficient as a function of velocity. The research was performed in ANSYS CFX software. The numerical simulations were performed for five chosen test speeds – 10, 40, 70, 100 and 130 km/h. The study provides analysis of static pressure distribution, velocity profile, velocity streamlines and turbulence intensity plots. The authors analyse the approximation method based on the obtained results of drag coefficients.
