INTRO Aerodynamic causes are caused by the relative motion of autos with atmosphere and they cause: п‚· Pull (resistance to forward motion) п‚· Lift up / down force (come into enjoy during cornering and acceleration) п‚· Assortment forces (comes into play during cornering) п‚· Occasions in spin, pitch and yaw As a result these elements have to be taken into account during vehicle design. THEORY BEHIND AERODYNAMIC FORCES The sources of sleek forces are п‚· Viscous forces п‚· Drag (form drag) Difficulties among both of these is the contact form drag caused by pressure dissimilarities between the front part and backside part of the motor vehicle.


In this project an effort is made to research the effects of car design about drag and down-force. A CFD evaluation of air flow around an automobile is completed using the next vehicle designs. п‚· 4x4 п‚· Four door п‚· Quickly sedan п‚· Sedan having a spoiler The first 3 are used to analyze drag plus the last can be used to study down-force. The following figures Fig. you, 2, a few, 4 demonstrate 2-D types of the above mentioned vehicle designs:

Fig. 1 A 2-D type of a ‘Jeep'.

Fig. two A 2-D model of a ‘Sedan'.

Fig. 3 A 2-D type of a ‘Fast Sedan'.

Fig. 4 A 2-D type of a four door with a back wing (spoiler).


The pressure field over the vehicles can be solved in the commercial software ANSYS. The following section describes the method used to resolve the pressure and speed fields.


 Creation of 2-D models of several vehicle style is accomplished in Pro-Engineer and imported to ANSYS  Answer domain (domain of interest) is created applying enclosures of required proportions and surroundings is chosen as its medium.  Meshing of the option domain is completed using automatic mesh generator. Initially a rough meshing performed and after reasonable solutions are obtained the mesh is made...
