Abstract: WOS: 000360219400006<br />This study presents experimental and numerical aerodynamic investigation of a prototype vehicle. Aerodynamics forces examined which exerted on a prototype. This experimental study was implemented in a wind tunnel for the Reynolds number between 105-3.1x10(5). Numerical aerodynamic analysis of the vehicle is conducted for different Reynolds number by using FLUENT CFD software, with the k-epsilon realizable turbulence model. The studied model aims at verifying the aerodynamic forces between experimental and numerical results. After the Reynolds number of 2.8x10(5), the drag coefficient obtained experimentally becomes independent of Reynolds number and has a value of 0.25.<br />Erciyes University [FBA-11-3453]<br />The authors would like to thank all students, designers and teachers involved in the Mobydick project. The authors would also like to thank to the Erciyes University research fund (project no: FBA-11-3453).
