Abstract Domain decomposition (DD) is a powerful approach to numerically solve partial
differential equations, and it has become popular and indispensable in simulations of fluid …

Microplastic (MP) particles are commonly found in freshwater environments such as rivers
and lakes, negatively affecting aquatic organisms and potentially causing water quality …

For simulating air-water flows with rigid-body motion, the rigid boundary has to be body-fitted
and discretized in the traditional dynamic mesh method, which will lead to a severe …

Abstract Domain composition methods (DCM) consist in obtaining a solution to a problem,
from the formulations of the same problem expressed on various subdomains. These …

A simple Chimera grid method is developed for complex flows with moving boundaries.
Based on the interpolation condition, a coupling strategy is proposed where algebraic …

A numerical solution procedure using the mesh-superposition approach, known as the
Chimera method, together with the OpenFOAM toolbox environment is used to compute the …

This paper presents a Chimera approach for the thermal problems in welding and metallic
Additive Manufacturing (AM). In particular, a moving mesh is attached to the moving heat …

The implementations of an updated body-fitted and a non body-fitted method to deal with the
interaction of a fluid and a rigid body are described. The physics of the fluid is modeled by …

One of the big challenges for offshore wave energy systems is how to guarantee the
survivability in harsh environmental conditions. Nonlinear and complex phenomena in steep …

Unlike the previous scientific works on the vertical axis turbines which were mostly limited to
design improvements, performance metrics and flow dynamics but significantly ignored the …
