• The rapid re-transmission of COVID-19 via close contact people is probable. • 1–50 μ m particles account for most of particles from a cough. • The high deposition rate in the oral/laryngeal region for droplets larger than 10 μ m warns of the easy expelling for re-transmission. • The re-transmission potential is estimated as 14.9% in the oral–nasa...

In the future, fossil fuels will be replaced by renewable sources. Hydrogen seems to be a promising energy carrier (fuel). A lot of research has been conducted on the combustion of hydrogen, but the effect of the high diffusivity of hydrogen compared to other species (differential diffusion) was often not included in simulations of turbulent flames...

In the present study, a finite volume method based on Reynolds-averaged Navier–Stokes equations is developed numerically in OpenFOAM to simulate two-phase flows around a freely floating cylinder in a numerical wave tank (NWT). All numerical computations are carried out using interDyMFoam solver, manipulating dynamic mesh. The left wall of NWT oscil...

Performance improvement of the pumps leads to the reduction in power consumption of industrial pumping systems. This paper presents an effective approach for the enhancement of the performance of a sanitary centrifugal pump by adopting computational fluid dynamics and response surface methodology with a multi-objective optimization algorithm. An ex...

This thesis investigates the aerodynamic and aeroacoustic prediction of vertical axis wind turbines, using computational fluid dynamics simulations. Noise pollution from wind turbines is one of the disadvantages of wind energy, calling for strategies to reduce noise levels. Yet for vertical axis wind turbines in particular, there is insufficient kn...

The paper presents the computational fluid dynamics simulation of an external gear pump for fluid power applications. The aim of the study is to test the capability of the model to evaluate the pressure in a tooth space for the entire shaft revolution and the minimum inlet pressure for the complete filling. The model takes into account the internal...

We present a new numerical simulation framework for prediction of flow patterns in the human left ventricle model. In this study, a radial basis function (RBF) mesh morphing method is developed and applied within the finite-volume computational fluid dynamics (CFD) approach. The numerical simulations are designed to closely mimic details of recent ...

To meet the timing resolution requirement of up-coming High Luminosity LHC (HL-LHC), a new detector based on the Low-Gain Avalanche Detector(LGAD), High-Granularity Timing Detector (HGTD), is under intensive research in ATLAS. Two types of IHEP-NDL LGADs(BV60 and BV170) for this update is being developed by Institute of High Energy Physics (IHEP) o...
