20.500.12556/DKUM-90163 Numerična simulacija aerodinamike dna dirkalnika Lotus 78 diplomsko delo Numerical simulation of the Lotus 78 floor aerodynamics V okviru diplomskega dela je opisana časovno neodvisna numerična simulacija aerodinamike dirkalnika dna Lotus 78. Na začetku diplomskega dela je opisano, zakaj je aerodinamika tako pomembna v motošportu in kateri so osnovni fizikalni zakoni, ki nam pomagajo bolje razumeti aerodinamiko. Prav tako je opisan postopek izvedbe numerične simulacije tekočin, ki vključuje ustvarjanje in uvoz geometrije, določanje robnih pogojev, izdelavo računske mreže in nastavitev simulacije. Izvedeni sta bili dve simulaciji, pri katerih je bila edina razlika v geometriji dirkalnika, tančneje v tako imenovanih zavesah na robu dna dirkalnika. Ugotovljeno je, da ti elementi igrajo pomembno vlogo pri aerodinamičnih silah in da lahko z učinkovito uporabo pozitivno prispevajo k zmogljivostim dirkalnika. As part of the diploma work, a time-independent numerical simulation of the aerodynamics of the Lotus 78 race car's underbody is described. At the beginning of the work, it is explained why aerodynamics is so important in motorsport and which basic physical laws help us better understand aerodynamics. The procedure for conducting fluid numerical simulations is also described, which includes creating and inputting geometry, determining boundary conditions, generating a computational mesh, and setting up the simulation. Two simulations were conducted, where the only difference was in the geometry of the race car, specifically the so-called skirts on the edge of the car's floor. It was found that these elements play a significant role in aerodynamic forces and that, with efficient application, they can positively contribute to the performance of the race car. numerična simulacija RDT aerodinamika Lotus 78 talni efekt Numerical simulation CFD aerodynamics Lotus 78. ground effect true true false [U.
