Air permeability is one of the most important parameters in the study of thermo-physiological comfort of fabrics. The main goal of this work is to develop a virtual process that allows the prediction of air permeability of any fabric without realizing a sample. The Free and Porous Media ... 詳細を見る

Using COMSOL Multiphysics, studies were performed showing that thermomagnetic siphoning (TMS) is a sufficient manner of regulating the temperature of a bundle of current-carrying wires wrapped with a magnetorheological fluid (MRF) jacket. Because of Curie’s Law, the cooler MRF on the ... 詳細を見る

The finite element method applied to the k-epsilon turbulence model is used to investigate the two-stream turbulent mixing layer. Whereas the model is known as one of the most popular of the turbulence models to date, the model has yet to be applied to the classical mixing layer problem ... 詳細を見る

Articular cartilage is composed by a charged solid matrix (proteoglycan and collagen fibres) and an interstitial fluid phase. The permeability of articular cartilage is a function of compression load applied on the tissue, the solid matrix underwent a compaction that decreased its value ... 詳細を見る

For the numerical solving of the equations, Comsol has been applied. Simulations have been modeled in 2D Cartesian, in cylindrical coordinate system and in a “mantle-like” cylindrical-shell. Mantle dynamics is controlled by the Rayleigh number (Ra), which is the ratio of the buoyancy ... 詳細を見る

In this context, a one-dimensional acoustic transmission line, exhibiting metamaterial properties, is presented. It is composed of an acoustic waveguide, periodically loaded with membranes having the function of series capacitances, as well as transversally connected open channels ... 詳細を見る

In this work we have constructed a 2D COMSOL model for the drying of Latex. It is based on a prior 1D model of Kiil, but also includes the effects of a flowing air stream, which is necessary to remove the evaporated water vapor. The model illustrates several features of drying that are ... 詳細を見る

The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of ... 詳細を見る

In this paper, a three-dimensional model of the coronary artery bifurcation is developed and physiological flow in the both healthy and stented coronary artery bifurcation is modeled using COMSOL Multiphysics. Wall shear stress induced by endovascular stents in the coronary artery ... 詳細を見る

In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and ... 詳細を見る
