Abstract:V okviru diplomskega dela je opisana časovno odvisna simulacija zaviranja dirkalnika Formule S. Na začetku je opisan projekt Formule S ter osnovni principi aerodinamičnih elementov. Opisani so načini izvajanja simulacije: urejanje geometrije, uvoz geometrije in izdelava računske mreže, določanje robnih pogojev in nastavitve časovno odvisne simulacije. Ugotovljeno je, da zaviranje vpliva na razmerje sil med sprednjimi in zadnjimi kolesi, kar sile pomakne proti slednjim, ter da se zaradi zaviranja tlačni koeficient na aerodinamičnih elementih zmanjšuje. Na začetku, razmerje sil med sprednjem in zadnjem delu avta znaša 58:42, po zaviranju pa 39:61, kar pomeni, da so v času zaviranja aerodinamični elementi učinkovitejši, saj v enem trenutku zaviranja dosežemo željeno razmerje sil.

Title:Numerical simulation of formula s aerodynamics
Abstract:As part of the diploma work, a time-dependent simulation of the braking of a Formula S car is described. At the beginning, information about the Formula S project and the basic principles of aerodynamic elements is provided. Then, methods of performing the simulation are described: geometry edit, importing the geometry and making the numerical mesh, determining the boundary conditions, and setting the time-dependent simulation. It has been found that braking affects the ratio of forces between the front and rear wheels toward rear, and that braking reduces the pressure coefficient of the elements. At first, ratio was 58:42, and after braking was 39:61, which means that aerodynamic elements are more efficient during braking, achieving desired force ration.
Keywords:Numerical simulation, CFD, transient simulation, Formula S, braking, aerodynamics
