TLDR
In this article, an immersed boundary formulation for three-dimensional incompressible flows is presented that uses the momentum equation to calculate the Lagrangian force field indirectly imposing the no-slip condition on solid interfaces.Abstract:
This paper presents an immersed boundary formulation for three-dimensional incompressible flows that uses the momentum equation to calculate the Lagrangian force field indirectly imposing the no-slip condition on solid interfaces. In order to test the performance of this methodology the flow past a sphere for Reynolds numbers up to 1,000 have been calculated. Results are compared with numerical data from other authors and empirical correlations available in the literature. The agreement is found to be very good.read more

Drag coefficient and Nusselt number for porous particles under laminar flow conditions
TL;DR: In this paper, the influence of particle porosity on particle-averaged drag coefficient and surface Nusselt number numerically Reynolds numbers considered are in the range of 10 Re 250 and up to 450 for specific porosities Fluid flow features inside the particles are explored using an immersed boundary method.

TL;DR: An immersed interface formulation that uses only a C 0 representation of the immersed interface, such as those provided by standard nodal Lagrangian finite element methods is introduced, and it is demonstrated that the method sharply resolves stress discontinuities along immersed boundaries while avoiding the need for analytic information about the interface geometry.

A p-multigrid strategy with anisotropic p-adaptation based on truncation errors for high-order discontinuous Galerkin methods
TL;DR: This paper introduces a multi-stage p-adaptation procedure which reduces the computational time when very accurate results are required and shows that a recently developed anisotropic truncation error estimator is perfectly suited to be performed inside the multigrid cycle with negligible extra cost.

Direct numerical simulations of three-dimensional flows past obstacles with a vortex penalization method
TL;DR: In this paper, a vortex method with penalization is proposed to simulate three-dimensional incompressible bluff body flows, which combines the robustness of vortex methods and the flexibility of penalization methods to impose boundary conditions on the obstacle.

Modeling Rotor Wakes with a Hybrid OVERFLOW-Vortex Method on a GPU Cluster
TL;DR: In this article, a hybrid Eulerian-Lagrangian method for modeling rotor wakes is proposed, which uses an anisotropic LES model to handle subgrid-scale dissipation explicitly, and uses a parallel adaptive treecode on a cluster of machines each with multi-core CPUs and multiple cost-efficient graphics processing units (GPUs).

On the identification of a vortex
Jinhee Jeong,Fazle Hussain +1 more
TL;DR: In this article, the authors propose a definition of vortex in an incompressible flow in terms of the eigenvalues of the symmetric tensor, which captures the pressure minimum in a plane perpendicular to the vortex axis at high Reynolds numbers, and also accurately defines vortex cores at low Reynolds numbers.
