Coaxial rotor systems are appealing for multirotor drones, as they increase thrust without increasing the vehicle’s footprint. However, the thrust of a coaxial rotor system is reduced compared to having the rotors in line. It is of interest to increase the efficiency of coaxial systems, both to extend mission time and to enable new mission capabilities. This study investigates how adjusting the pitch of the lower rotor relative to that of the upper one impacts the overall efficiency of the system. A coaxial rotor system for a medium-sized drone with a rotor diameter of around 70 cm is used.For the CFD…

Y-Pipe structures are widely used in many manufacturing and research areas for mixing different reactants solutions. The flow behaviors inside a Y-Pipe are worth studying to improve the mixing efficiency and control the flow properties. In this study, two different configurations of Y-Pipes are investigated. This structure is used for biomaterial production. Each pipe has varying cross-sections with restrictions and enlargements, which require very subtle handling of the near-wall regions to obtain high-quality mesh. The mixing chamber in the middle needs a particularly careful setup.FidelityTM Pointwise® is used for the mesh generation in the two Y-Pipes. The T-Rex function of Pointwise…
