Abstract

The paper presents the mechanism of wing in ground effect formation, also shows the structure of wing in ground craft, and race car, which uses wing in ground effect. Results of numerical analysis are as expected, which means, the lift coefficient is higher for positive angles of attack, and lower for negative angles of attack. The paper details also characteristics of lift and drag coefficients in angle of attack function. The numerical research was conduct in Ansys Fluent 15.0 academic license.
