The analysis is performed for an Ahmed body, for which the measurement results and a variety of numerical simulations are available in the literature. The results of the stationary CFD simulations with the RANS approach show a significant difference between the results obtained with the SolidWorks Flow Simulation 2014 software and ANSYS Fluent 16.2 software in the air flow analysis area from 10 m/s to 60 m/s. The difference in computational time is also apparentV članku primerjamo rezultate CFD simulacij, pridobljene s pomočjo dveh različnih programskih paketov za numerično dinamiko tekočin. Analiza je izvedena za Ahmedovo telo, za katerega so v literaturi na voljo tako rezultati simulacij, kakor tudi meritev. Rezultati CFD simulacij kažejo na signifikantno razliko med rezultati, ki smo jih pridobili s programsko opremo SolidWorks Flow Simulation 2015 in s programsko opremo ANSYS Fluent 16.2 v analiziranem območju toka zraka od 10 m/s do 60 m/sTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
