This paper aims to analyze the fluid dynamic behavior of a downhill skateboarding helmet through CFD simulations performed with ”Kratos Multiphysics”. FEM techniques have been considered for solving the Navier-Stokes equations, comparing Body-Fitted and Embedded methods for the evaluation of forces on the body. The primary objective, in addition to an enhancement of personal knowledge and a study of the operating principles of fluid dynamics simulation software in preparation for master’s studies, is to evaluate the differences between the various resolution methods used, highlighting how the solver’s choice can significantly influence the quality and effectiveness of the simulation.
L’elaborato si propone di andare ad analizzare il comportamento aerodinamico di un casco da downhill skateboarding attraverso simulazioni CFD svolte con il software ”Kratos Multiphysics”. Sono state considerate tecniche FEM per la risoluzione delle equazioni di Navier-Stokes, confrontando metodi Body Fitted ed Embedded per la valutazione delle forze sul corpo. L’obiettivo principale, oltre ad un accrescimento delle conoscenze personali e a una ricerca sui principi di funzionamento dei software di simulazione fluidodinamica in vista degli studi magistrali, è valutare le differenze tra i vari metodi di risoluzione utilizzati, analizzando come la scelta del risolutore possa influenzare sensibilmente la qualità e l’efficacia della simulazione.

Abstract
This paper aims to analyze the fluid dynamic behavior of a downhill skateboarding helmet through CFD simulations performed with ”Kratos Multiphysics”. FEM techniques have been considered for solving the Navier-Stokes equations, comparing Body-Fitted and Embedded methods for the evaluation of forces on the body. The primary objective, in addition to an enhancement of personal knowledge and a study of the operating principles of fluid dynamics simulation software in preparation for master’s studies, is to evaluate the differences between the various resolution methods used, highlighting how the solver’s choice can significantly influence the quality and effectiveness of the simulation.| File | Dimensione | Formato | |
