The correlation between numerical and experimental tests, including road tests, smoke and water jet tests, etc. will be highlighted. Two types of vortex generators have been tested, from which high decreases in the drag coefficient in the virtual tests by means of CFD tools were obtained. These vortex generators, are one co-rotational with blade shape VG and the other one with a complex geometry, manufactured by the Air Tab Company. On the other hand, some new low-cost experimental tests have been planned. They do not include the use of a wind tunnel. It has also been necessary to build some functional prototypes of the VGs. It must be highlighted that the use of these types of tests stems from the need to obtain experimental test results to be compared with the numerical results. It must also be pointed out that, due to their high costs, wind tunnel tests have not been conducted to validate the numerical results. However, road test results have proved useful in obtaining the behavior and aerodynamic improvements of the VGs. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.562 2018 ENGINEERING, MULTIDISCIPLINARY 82 / 88 = 0.932 2018 Q4 T3 0.136 2018 Engineering (miscellaneous) 2018 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-8451-660X Ranz Angulo, David Universidad de Zaragoza (orcid)0000-0002-4268-7424 Peña Baquedano, Juan Antonio Universidad de Zaragoza 5002 305 Universidad de Zaragoza Dpto.
