This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into ... 詳細を見る

This app demonstrates the following: Importing measured data from a text file Handling measured data using methods Exporting the results to a text file Exporting the results as COMSOL Material Library file. The app is a companion to the Effective Nonlinear Constitutive Relations ... 詳細を見る

A mode analysis study is used to find the complex effective indices for a microstructured optical fiber (MOF), consisting of air holes in a silica host. As the effective index is smaller than the refractive index of the silica background material, the modes are leaky. The model ... 詳細を見る

This example models a solid oxide electrolyzer cell wherein water vapor is reduced to form hydrogen gas on the cathode, and oxygen gas is evolved on the anode. The current distribution in the cell is coupled to the cathode mass transfer of hydrogen and water and momentum transport. Two ... 詳細を見る

This model shows how to use the scattered field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite size phononic crystal. The transmission tends to zero in the frequency range corresponding to P- and S-wave band gaps, as ... 詳細を見る

Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface. This example illustrates the modeling of such a CVD reactor where triethyl-gallium first decomposes, and the reaction products ... 詳細を見る

Sound is generated by a point source located in the wall of this test bench car interior. The sound pressure level response at a point of measurement is investigated for a range of frequencies and four different mesh resolutions. The model is first solved with the default direct solvers. ... 詳細を見る

This example describes the operation of a drug delivery system that supplies a variable concentration of a water soluble drug. A droplet with a fixed volume of water travels down a capillary tube at a constant velocity. Part of the capillary wall consists of a permeable membrane ... 詳細を見る

One way to generate circular polarization from a microstrip patch antenna is to truncate the patch radiator. This model is tuned around the GPS frequency range. The axial ratios are calculated to show the degree of circular polarization. 詳細を見る

This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The ... 詳細を見る
