Abstract: A hydraulic jump is a common phenomenon that can be observed in open channel flows such as rivers and spillways. It can cause damage of the downstream bed and bank of the channel due to the process of continuous erosion ...

Abstract: To protect laborers in a working environment containing toxic vapor, particles and contaminants, an efficient ventilation facility is essential. A well-designed industrial ventilation facility should ...

Abstract: Dynamic stall is a nonlinear fluid phenomenon. It is caused by the vortex generation and motion of the leading edge of the wing. When the angle of attack (AOA) changes rapidly, it causes the vortex to delay and shed. ...

Abstract: The control of volume flow rate in a ball valve is very important when a ball valve is utilized in a piping system. It is difficult to linearly control the flow rate in a ball valve ...

Abstract: The aim of this study was to prove that an optimization method combining genetic algorithms with a direct-forcing immersed boundary method as a distinguished numerical method could improve the performance of vertical-axis ...

Abstract: Cavitation in a valve leads to trouble and inconvenience for factories. Valves in a piping system are ruined, leading to costly replacements every several months. To reduce the cost caused by cavitation in a valve, a cage ...

Abstract: A numerical simulation is carried out to investigate the effect of inlet port cross-section geometry on the in-cylinder flow of a motored four-valve, single-cylinder, four-stroke internal combustion engine during the intake ...
