Abstract
The simulation of flows using computational fluid dynamics (CFD) has advanced considerably in recent decades and is now an essential tool across industries ranging from aerospace design to process engineering. Although CFD is relatively mature for single-phase flows, multiphase flows (such as particle-laden flows) and multiphysics flows (such as those including microwaves or ultrasound) remain significantly more challenging to simulate, in part due to their intrinsic multiscale nature and conflicting numerical need.
In the recent years, high-order methods have gained considerable momentum in aeronautics, in part due to their significantly lower dispersion and dissipation, but also for their higher arithmetic intensity (FLOPS-to-byte ratio) which suits current hardware capabilities. However, these methods remain seldomly used in chemical-engineering applications, in part due to their multiphase and multiphysics nature.
