[3] XYZ Scientific Applications, Inc., Livermore, CA, USA

Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to ... En savoir plus

SD Numerical Simulation Technique for Hydrodynamic Flow Gas-Solids Mixing

I. Mantilla[1], S. De Vicente[2]
[1]National University of Engineering, Lima, Perú
[2]Polytechnic University of Madrid, Madrid, Spain

We formulate a new mathematical model of gas-solids mixing hydrodynamic flow [1] in a combustion chamber with a fluid bed system used in the combustion of mineral coal waste. This model in study is called Model Gas-Solids Mixing and it is constructed by averaging the conservation ... En savoir plus

Application of the Hot Wire Technique and COMSOL Multiphysics for Heat Transfer Monitoring in Solids

J. Hernandez[1], V. Suarez[1], J.A. Calderon[1], E. Marin[1], B. Rojas[1], A.G. Juarez[1], J. Guarachi[1]
[1]Centro de Investigación en Ciencia Aplicada y Tecnología Avanzada Unidad Legaria del Instituto Politécnico Nacional, Mexico, Distrito Federal, Mexico

We applied the Hot Wire (HW) technique and COMSOL Multiphysics software to study the heat transfer of a homogeneous and isotropic solid material. The HW technique is based on the application of a linear power density modulated by a rectangular pulse of heat, in a specific time period. ... En savoir plus

A Study on Hydrodynamics of Melt Expulsion in Pulsed Nd: YAG Laser Drilling of Titanium

S. Sharma [1], Y. Pachuary [2], S. N. Akhtar [3], J. Ramkumar [1],
[1] Indian Institute of Technology Kanpur, Kanpur, India
[2] Indian Institute of Information Technology, Design and Manufacturing, Jabalpur, India
[3] Integral University, Lucknow, India

Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon ... En savoir plus
