An Original Way of Using COMSOL Multiphysics® Application Builder to Enhance Simulation of Laser Welding

Y. A. Mayi1, M. Dal1, P. Peyre1, M. Bellet2, C. Metton3, C. Moriconi3, R. Fabbro1
1Laboratoire PIMM, Arts et Metiers, Paris, France
2CEMEF, MINES ParisTech, Sophia Antipolis, France
3Safran Additive Manufacturing, Paris, France

The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... En savoir plus

The use of 3D printed material for trunk exoskeleton system

M. Dickinson1, E. Sanderson1
1University Of Central Lancashire, United Kingdom

Since the 60’s, exoskeleton technology has fascinated scientists and engineers alike, from examples such as the early GE “Handyman” through to model XOS, a military grade heavy duty system. This technology can also be found in the clinical setting, where systems can offer patients, who ... En savoir plus

Direct Optical Surface Roughness Modeling

T. Tran1, S. Peana1, A. V. Kildishev1
1Purdue University, West Lafayette, IN, USA

Optical devices are generally simulated using ideal structures. These ideal geometries are critical in finding major features of the optical response. Unfortunately, fabrication of such devices rarely results in structures that are ideal.[1] In particular, surface roughness is rarely ... En savoir plus

Modeling the effects of electromagnetic fields on biological structures on the order of the body and tissues to the micro (1e-6)-and nano (1e-9) level of cells and sub-cellular structures presents formidable challenges. We share the major lessons we have learned using COMSOL ... En savoir plus

Sound Generated by Quadrupole Near Object

M. Hashiguchi1, D. Mi1
1Keisoku Engineering System Co. LTD., Chiyoda-Ku, Tokyo, Japan

Aerodynamic sound is generated by unsteady fluid motion and enhanced when the flow becomes turbulent. For example, drone is loud because the ambient air is stirred by their propeller to get lift and movement and the air becomes turbulent. Reduction of aerodynamic noise is an important ...

Extended Surface Heat Transfer from and Thermal Stress in Radial Fins

E. Gutierrez-Miravete1, A. Campo2
1Rensselaer at Hartford, Hartford, CT, USA
2University of San Antonio, San Antonio, TX, USA

Radial fins are widely used in industrial applications to enhance heat transfer. Exact solutions are available for radial fins of simple profiles such as rectangular, concave and convex parabolic, hyperbolic and triangular. However, such solutions may be cumbersome for use in everyday ... En savoir plus

CFD Studies of Educational Closed Loop Water Tank

R. Wulandana1
1State University of New York, New Paltz, NY, USA

This paper describes the utilization of COMSOL Multiphysics® package for the finite element modeling of an educational closed-loop water tank. The custom water tank was built to be part of the fluid mechanics lab belonging to the Mechanical Engineering Program of SUNY New Paltz, NY. The ... En savoir plus

Fully Coupled Hydro-Mechanical Modeling of Hydraulic Fracturing in Barnett Shale Formation

M. Jarrahi1, H. M. Holländer1
1University of Manitoba, Winnipeg, MB, Canada

The unconventional shale gas reservoirs have a major contribution to hydrocarbon production in recent years. The hydraulic stimulation technique is being used to enhance the productivity of the target reservoirs. The drilled wellbore and existing natural fractures in the host rocks have ... En savoir plus

Investigation of 1D Compressible Navier Stokes Using Equation-Based Modeling

J. D. Freels1, A. J. Baker1
1University of Tennessee, Knoxville, TN, USA

A fundamentally important area of the COMSOL Multiphysics® code is that of equation-based modeling. This root capability is unique in commercially-available codes and offers unlimited application. One specific area that requires more detail, even in the CFD Module of COMSOL®, is that ... En savoir plus

Predictive Analytics and Uncertainty Quantification of a Microscale Porous Reactor Simulation

G. Jones1, R. McConnell1
1SmartUQ, Madison, WI, USA

The use of computer simulations to analyze systems during the design process is a popular approach for validating and optimizing designs. But simulations are deterministic in nature and do not consider the uncertainty in design, manufacturing, and use of the product. Using predictive ... En savoir plus
