Topology optimization of impeller blades in baffled stirred tanks
An approach for the numerical topology optimization of baffled stirred tanks is presented and demonstrated exemplarily on impeller blades. The methodology is based on the well-known Brinkman penalization method, which is used to alter the impeller blade ...

Lagrangian Numerical Methods for Ocean Biogeochemical Simulations [PDF]
We propose two closely--related Lagrangian numerical methods for the simulation of physical processes involving advection, reaction and diffusion. The methods are intended to be used in settings where the flow is nearly incompressible and the P\'eclet ...

Numerical Modelling of Microstructure Evolution in Friction Stir Welding (FSW)
This work studies the metallurgical and microstructural aspects of Friction Stir Welding (FSW) in terms of grain size and microhardness. The modelling is based on the combination of an apropos kinematic framework for the local simulation of FSW processes

Effect of the Tool Tilt Angle on the Heat Generation and the Material Flow in Friction Stir Welding
This work studies the effect of the tool tilt angle on the generated heat and the material flow in the work pieces joint by Friction Stir Welding (FSW). An apropos kinematic framework together with a two-stage speed-up strategy is adopted to simulate the

Warpage Analysis and Control of Thin-Walled Structures Manufactured by Laser Powder Bed Fusion
Thin-walled structures are of great interest because of their use as lightweight components in aeronautical and aerospace engineering. The fabrication of these components by additive manufacturing (AM) often produces undesired warpage because of the ...

A robust algorithm for implicit description of immersed geometries within a background mesh
The paper presents a robust algorithm, which allows to implicitly describe and track immersed geometries within a background mesh. The background mesh is assumed to be unstructured and discretized by tetrahedrons.

Numerical methods for one-dimensional aggregation equations [PDF]
We focus in this work on the numerical discretization of the one dimensional aggregation equation $\pa_t\rho + \pa_x (v\rho)=0$, $v=a(W'*\rho)$, in the attractive case.
