In recent years, ventricular assist devices (VADs, also known as blood pumps) have
gradually entered clinical practice and provide effective treatment for heart failure patients …

This text presents contributions to efficient high-order finite element solvers in the context of
the project ExaDG, part of the DFG priority program 1648 Software for Exascale Computing …

The present work develops hybrid multigrid methods for high-order discontinuous Galerkin
discretizations of elliptic problems, which are, for example, a key ingredient of …

We consider a Leray model with a nonlinear differential low-pass filter for the simulation of
incompressible fluid flow at moderately large Reynolds number (in the range of a few …

Abstract The Food and Drug Administration's (FDA) benchmark nozzle model has been
studied extensively both experimentally and computationally. Although considerable efforts …

Onset of flow transition in a sinusoidally oscillating flow through a rigid, constant area
circular pipe with a smooth sinusoidal obstruction in the center of the pipe is studied by …

Abstract Machine learning (ML) has benefited from both software and hardware
advancements, leading to increasing interest in capitalising on ML throughout academia …

Numerical flow simulations that analyze the turbulent flow characteristics within a turbopump
are important for optimizing the efficiency of such machines. In the case of ventricular assist …

Background and objective: Contrary to flows in small intracranial vessels, many blood flow
configurations such as those found in aortic vessels and aneurysms involve larger Reynolds …

Flows through medical devices as well as in anatomical vessels despite being at moderate
Reynolds number may exhibit transitional or even turbulent character. In order to validate …
