This article addresses the study of internal flow dynamics within a cryogenic chamber designed for freezing food using liquid nitrogen injection. The chamber features a circular section with strategically placed jet-type atomizers for this purpose. The primary objective is to extend the residence time of the cryogenic fluid within the chamber to en...

The utilization of unmanned sailboats as a burgeoning instrument for ocean exploration and monitoring is steadily rising. In this study, a dual sail configuration is put forth to augment the sailboats’ proficiency in its wind-catching ability and adapt to the harsh environment of the sea. This proposition is based on a thorough investigation of sai...

Water, vital for life, is largely unusable despite being renewable. Growing populations, urbanization, and pollution continually deplete the world’s drinking water supply. A third of the global population faces freshwater scarcity. Natural sources can’t fully meet demand, necessitating efficient water desalination. Solar stills, utilizing solar des...

Hlavním cílem této bakalářské práce je změnit profil křídla rychlostního letounu navrženého v diplomové práci Ing. Jakuba Valenty tak, aby se zlepšili jeho aerodynamické vlastnosti za provozních podmínek. Prvním krokem je výpočet hodnot, dle kterých se bude profil optimalizovat. Na základě těchto výpočtů je zvolen nový profil, který je porovnáván s...

Úkolem této práce je aerodynamický návrh nového trupu rychlostního letounu. Je proveden návrh pozice pilota, ze které následně vychází návrh trupu. V rámci analýzy programem Ansys Fluent je provedena validace výpočetního modelu na experimentálně získaných datech. Následuje výpočet aerodynamických součinitelů původního letounu. Dále jsou provedeny v...

Currently, the process of creating industrial installations is associated with digital technologies and must involve the stage of developing digital models. It is also necessary to combine installations with different properties, functions, and operational principles into a single system. Some tasks require the use of predictive modeling and the cr...

This thesis investigates a novel load alleviation technique known as mini-tabs, small devices placed on the upper surface of wings to reduce lift. Reynolds-Averaged Navier-Stokes (RANS) simulations were conducted to analyze the impact of geometrical properties on mini-tab performance in reducing the load on a wing.
The initial simulations focused on...

Due to global warming concerns, the Aviation industry is trying to reduce its carbon footprint. Electric propulsion (EP) is one way of doing this, where the power is obtained from electrical sources. The concept of distributed electric propulsion (DEP) is in the focus now. NASA’s X-57 Maxwell, a high winged, all-electric experimental aircraft, uses...

CFD models of intakes in high-head hydropower systems are rare due to the lack of geometric data and cost of modeling. This study tests two different types of software to see how modeling can be performed in a cost-effective way with scarce input data and still have sufficient accuracy. The volume of fluid (VoF) model simulations are conducted usin...

Flow studies in control structures require the development of nonlinear differential equations that have no analytical solution but can be approximated by applying the finite volume method in mathematical models such as Fluent. This article presents a comparative analysis between a numerical model and a physical model of water flow in a laboratory ...
