We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate. Mehr lesen
Industrial fluid systems often involve continuous piping loops. These systems consist of varying lengths of pipes and hoses connecting multiple components together. Fluid resonances can detrimentally affect the operation of fluid systems and components. This work used COMSOL to ... Mehr lesen
We present an optimization procedure to improve the propagation properties of the depressed-cladding, buried micro-structured waveguides formed in a z-cut lithium niobate (LN) crystal by high repetition rate femtosecond (fs) laser writing. It is shown that the propagation wavelength ... Mehr lesen
Char combustion is one of the most important reactions in the process of Underground Coal Gasification (UCG). Experiments are performed in a boat reactor under near isothermal condition to demonstrate effects of heat and mass transfer and bed diffusion through ash layer. To obtain a ... Mehr lesen
Three-dimensional finite element (FE) modeling of magnetic flux leakage (MFL) technique has been performed using COMSOL 3.4 for prediction of leakage fields from surface and sub-surface defects in a 12 mm thick carbon steel plate. The tangential and normal components of leakage fields ... Mehr lesen
Nematic Elastomers (NEs) possess both the elastic properties of rubbers and the orientational properties of liquid crystals. Those two properties makes the configuration of NEs very sensitive to isotropic-nematic phase transition. Our goal is to replicate with numerical experiments the ... Mehr lesen
Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... Mehr lesen
Safe short term storage of CO2 depends mainly on structural and solubility trapping. On longer term, mineral trapping is also contributing to the trapping of CO2. To be able to investigate the importance of these different storage mechanisms, a finite element model for simulation of CO2 ... Mehr lesen
We present quantitative nano-scale analysis of the 3D spatial structure of an anticorrosive aluminium epoxy barrier marine coating obtained by ptychographic X-ray computed tomography (PXCT) [1-3]. We then use COMSOL Multiphysics® software to perform simulations on the acquired real 3D ... Mehr lesen
All particles in suspension have a zeta potential, or surface potential. Its measurement is extremely important for predicting the formulation stability across a wide range of industries including food, ink and pharmaceuticals, water purification and medical devices. Zeta potential is ... Mehr lesen
