Thermo-Fluid-Metallurgical Modeling and Parametric Study of Laser-Based Powder Bed Fusion Process

M. Bayat [1], S. Mohanty [1], J. H. Hattel [1],
[1] Department of Mechanical Engineering, Technical University of Denmark, Lyngby, Denmark

Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... En savoir plus

Conjugate Heat Transfer Simulation of Argon Gas Heater for ARPS in Pyroprocessing Facility

[1] Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

PyroProcessing Research and Development Facility (PPRDF) is being setup in IGCAR to develop pyroprocessing technology. It consists of a large argon cell attached with Argon Recirculation and Purification System (ARPS). Once through Argon gas heater is an important process equipment in ... En savoir plus

Simulation of a Vortex Ring: Dealing with the Unbounded, Doubly Connected Domain

J. M. Russell [1],
[1] Emeritus Professor, Florida Institute of Technology, Melbourne, FL, USA

This talk is for intermediate-level users of COMSOL who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. Most turn-key Computational Fluid Dynamics packages, including COMSOL ... En savoir plus

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J. Wheeler [1]
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... En savoir plus

Flow Optimization of a MVHR Combined with an Exhaust Air Heat Pump by Means of CFD Simulation

F. Ochs [1], M. Bianchi Janetti [1], M. Romani [2],
[1] University of Innsbruck, Unit Energy Efficient Buildings, Austria
[2] Galletti Group, Italy

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus

Fluid Dynamics of Blood Flow during Reperfusion and Post-conditioning

T. Merrill[1], A. La Barck[1], and J. Docimo[2]
[1]Rowan University, Glassboro, New Jersey, USA
[2]FocalCool, LLC, Mullica Hill, New Jersey, USA

Reperfusion injury is caused by the rapid restoration of blood flow to oxygen-starved tissue. Animal studies show that intermittent periods of occlusion (also called post-conditioning) during reperfusion can limit tissue damage to vital organs such as the heart and brain. These studies ...
