This example of turbulent flow in a partially baffled turbulent mixer with a three-bladed impeller shows how to set up the Rotating Machinery, Turbulent Flow interfaces from the Mixer Module with a Level Set method for free surface flow in a rotating geometry. A time-dependent simulation ... Mehr lesen
Eine akustische Oberflächenwelle (surface acoustic wave, SAW) ist eine akustische Welle, die sich entlang der Oberfläche eines festen Materials ausbreitet. Ihre Amplitude nimmt in der Tiefe des Materials schnell, oft exponentiell, ab. SAWs werden in vielen Arten von elektronischen ... Mehr lesen
A surface mount resistor is subjected to thermal cycling. The difference in the thermal expansion of different materials will introduce stresses in the structure. The solder which connects the resistor with the printed circuit board is seen as the weakest link in the assembly. It ... Mehr lesen
In this tutorial, the eigenmodes and eigenfrequencies of an air bubble in water is modeled and compared with analytical solutions. The effects of surface tension is included and allows to model both the pulsating mode and the surface modes of the bubble. Lastly, the effect of the ... Mehr lesen
In the surface acoustic waves industry different crystal cuts of piezoelectric materials are used, e.g. 128ᵒ YX LiNbO3, AT&ST quartz, 42ᵒ YX LiTaO3, etc. Direct data isn’t available for all cuts. The standard approach is to use the so-called Euler angle rotation. COMSOL supports it ... Mehr lesen
All integrated circuits (ICs) — especially high-speed devices — produce heat. In today’s dense electronic system layouts, heat sources are many times placed close to heat-sensitive ICs. Designers of printed circuit boards often need to consider the relative placement of heat ... Mehr lesen
This model simulates a negative dielectric barrier discharge under a point-to-plate electrode configuration. Two solid dielectric layers are inserted into the air gap. A negative voltage of 2.5 kV is applied to the cathode electrode, initiating a corona streamer that propagates and ... Mehr lesen
This model shows how to use the features of the Heat Transfer Module to reduce the computation time and memory usage in view factor computations. Illustrative results of speedup and memory usage reduction are given on a benchmark model. The solution is not computed, only the view ... Mehr lesen
This tutorial model demonstrates the use of the Moisture Flow coupling node to account for the Stefan flow in moist air, over an evaporation surface. The effects on the velocity field and vapor concentration are presented with different ambient temperature conditions. Mehr lesen
This model computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.7 (heavily oxidized). A more ... Mehr lesen
