Persistent organic pollutants (POPs) are increasing in waterways due to human activities
and their concentration above a certain level is highly toxic with acute damage. In this …

The finite-time Lyapunov exponent (FTLE) method is a mature and practical method for
analyzing the characteristics of Lagrangian coherent structures. It can be used for studying …

Phosphorite mineral is the most important natural source of phosphorus (P) which has
several applications in agriculture (as fertilizers), pottery, and animal feed. Phosphorite …

A Lagrangian method is introduced to analyze the tip leakage vortex (TLV) behavior in a low-
speed axial compressor rotor. The finite-time Lyapunov exponent (FTLE) fields are …

In this work, a discrete gas-kinetic scheme (DGKS) based on the arbitrary Lagrangian–
Eulerian (ALE) method is proposed for the simulation of moving boundary problems. The …

The twin-screw multiphase pump shows a significant phenomenon of fluid–thermal–
structure physics field coupling. The method of studying dynamics, thermodynamic …

Unphysical numerical oscillations (UNOs) arise when a non-dissipative scheme is employed
to discretize fluid equations on a coarse grid. Treating UNOs often relies on upwind …

Activated carbon (AC) is a versatile material which is generally prepared from sustainable
carbon resources and is sometimes referred to as activated charcoal, activated coal …

Fluid in a turbulent state will be continuously stretched and folded, and the boundaries of
fluid elements will grow exponentially, leading to an intense mixing process between …

The exponential population growth and social civilization expansion, changes in lifestyles
and resource consumption, and continuous development of industries and technologies …
