Steam–water injectors have been widely applied in various industrial fields because of their compact and passive features. Despite its straightforward mechanical design, the internal two-phase condensing flow phenomena are extremely complicated. In

Classical models of subatomic particles [PDF]
We look at the program of modelling a subatomic particle---one having mass, charge, and angular momentum---as an interior solution joined to a classical general-relativistic Kerr-Newman exterior spacetime. We find that the assumption of stationarity upon which the validity of the Kerr-Newman exterior solution depends is in fact violated quantum ...

Ecohydrological particle model based on representative domains [PDF]
Non-uniform infiltration and subsurface flow in structured soils is observed in most natural settings. It arises from imperfect lateral mixing of fast advective flow in structures and diffusive flow in the soil matrix and remains one of the most ...

Long-lived particle phenomenology in the 2HDM+a model
Higgs decays displaced from the primary interaction vertex represent a striking experimental signature that is actively searched for by the ATLAS, CMS and LHCb collaborations.

Advanced Porous Particle Model in Biomass Pyrolysis
In order to decrease anthropogenic CO2 emissions and to become independent from fossil resources, one alternative for energy generation and production of platform-chemicals is the usage of biomass.

Improved Interacting Multiple Model Particle Filter Algorithm [PDF]
For the issue of limited filtering accuracy of interactive multiple model particle filter algorithm caused by the resampling particles don't contain the latest observation information, we made improvements on interactive multiple model particle filter ...

Assessment of Contact Laws Accounting for Softening in 3D Rigid Concrete Particle Models
To obtain predictions closer to concrete behaviour, it is necessary to employ a particle model (PM) that considers contact softening. A bilinear softening contact model (BL) has been adopted in PM studies.
