Abstract

The study of drag and lift coefficients as well as pressure distribution on the surface of a road vehicle is mainly done by the analysis of their aerodynamics. In this work, an aerodynamic comparative study is done on three different shapes of cargo truck tricycles, with the major difference being their frontal shapes. CAD models of the cargo truck tricycles were created using Creo Element/Pro 5.0 Software. The Computational Fluid Dynamics (CFD) simulation was done using Solidworks software. An external flow analysis was carried out for speeds of 40kmph, 60kmph, 80kmph, 100kmph and 120 kmph. The value of coefficient of lift to coefficient of drag ratio is plotted against speeds and compared. Pressure and velocity distribution were analyzed for each body shape in relation to fluid flow, drag and lift force. A model with good economic value is the best choice. Model 3 possesses the best aerodynamic features of the three models created.
