Práce a štúdie - Vydanie 9, 2021 Higher awareness of aviation sustainability and environmental impact creates more research on profile drag reduction. The basic principles of aerodynamic profile drag are described and its role within the total drag. The boundary layer is defined using mathematical and physical principles of fluid dynamics.

On the aerodynamics drag of floorball [PDF]
AIP Conference Proceedings, 2020 Floorball is a developing sport that have been popular the last few years. As the game continues to grow, the demand for a better performance is growing to meet the hype of a better gameplay. The geometry of floorball ball is clasified as unique as it is hollow and contoured by holes.
