Diffuser Design for PACE Global Formula One Racer

The detailed design process of the diffuser for a Formula one racer is described. It begins with the study of overall aerodynamic performance and follows the basic function of the diffuser. And then forms the strategy for such a diffuser which should perform the maximum downforce. Then is the detailed analysis of diffuser by two different methods of development. The small-scaled wind tunnel data is presented, together with the CFD analysis, describing the major consideration in using these two developing methods and demonstrating the major influence for the diffuser design.
