We present numerical results involving microorganisms adhering to a plane surface submitted to a shear flow. The purpose is to have a better understanding of the removal mechanisms occurring during the cleaning in place of food processing equipments. The biological cell, i.e. the ... 詳細を見る

This paper shows a model to estimate the scaling parameters for reverse osmosis membrane processes. The model takes into account the concentration polarization of ionic species in the membrane channel of spiral-wound modules and the effect of the spacers on the flow. The scaling ... 詳細を見る

Ventilation is mainly used to control indoor air quality and for the purpose of thermal comfort by diluting and displacing pollutants. Because of the effects it has on health, comfort, and serviceability, indoor air quality in our homes is becoming of increasing concern to many people. ... 詳細を見る

This work enunciates the principles of SAW design from a physical perspective, examining the standard engineering modelling assumptions in some detail. An integral form analytical expression based on 2D elastic isotropic theory is validated against a COMSOL Multiphysics® simulation, ... 詳細を見る

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import ... 詳細を見る

Usually, in integrated circuits, the chip is brazed on leadframe and then, a polymer resin is molded around to create the packaging. On the first hand, the molding process at high temperatures will induce thermomechanical stress on the chip. As the leadframe, the chip and the braze have ... 詳細を見る

In one of the screw compressor system, designed silencer was not optimal. A great challenge was the large variation in operating conditions, especially the variation of the molecular weight of the gas. There was need to optimize the silencer. This paper describes the acoustic modelling ... 詳細を見る

The 3D unit cell model approach offers an efficient tool to analyze the influences of geometrical design (channel shape and arrangement, filter length, wall thickness) and filter material properties (permeability, soot loading characteristics) on the performance of ceramic particle ... 詳細を見る

In this session, we will discuss and showcase a few examples of advanced acoustics applications. In this context, “advanced” means problems that cannot simply be modeled “out-of-the-box,” but require the flexibility and strengths of COMSOL Multiphysics® software. Topics include: • ... 詳細を見る

Simulation on loudspeaker drivers require a conventional fully coupled vibro-acoustic model to capture all effect. An accurate vibroacoustic model can be time-consuming to solve, especially in 3D. In practical applications, this results in poor efficiency concerning the decision-making ... 詳細を見る
