Introduction

In patients with moderate symptomatic or severe asymptomatic carotid stenosis, prior to an endarterectomy it is recommended to do a detailed study, in which the complet set of morphological and hemodynamic parameters are included.

In this work the [...]

Abstract

The energy use in buildings has to be decreased to reach the targets and regulations in the European Union. One way of reducing the energy demand is to use vacuum insulation panels (VIP) in the building envelope. To make sure the declared thermal properties of the VIP are valid for [...]

Abstract

This paper analyzes the ability of the Lattice Boltzmann method (LBM) with multiple relaxation times (MRT) in the simulation of flow in practical engineering problems. The case study covered refers to the first section of the initiation channel, which is part of the piracema channel, [...]

Abstract

A finite element model has been developed for the 3D simulation of the sintering of a single track during a selective laser sintering process (SLS). The model takes into account both the [...]

Abstract

Residual stresses and distortions are two technical obstacles for popularizing the additive manufacturing (AM) technology. The evolution of the stresses in AM components during the thermal [...]

Abstract

In this study, a numerical approach is developed to simulate the molten pool formation during the melting of a powder bed. It is based on a fluid formulation that allows taking into account the dynamics in the molten pool through the two effects of surface tension (including both [...]

Abstract

In this paper, we firstly introduce a nodal-integration-based finite element method. The method allows the use of first-order tetrahedral elements without suffering from the volumetric locking problem. The most important advantage of tetrahedral meshes is that they can be automatically [...]

Abstract

The aviation industry found that a number of engine power-loss events were related to the ice crystal icing, and the research on ice crystal icing had gradually attracted the attention of scholars. In this work, the compressor and ice crystals ingested are regarded as study objects, [...]
