A scanning electron microscope samples images by scanning a target with a high-energy beam of electrons. The subsequent electron interactions produce signals such as secondary and back-scattered electrons that contain information about...
Estimating center-of-mass coordinates and the spatial extent of iron-rich layers helps decrease the cost of exploration. Magnetic prospecting is applicable for doing this for certain types of iron ore deposits. Passive magnetic...
The development of mixers does often not only have to account for effectiveness, but also other factors must be involved, such as cost and complexity for manufacturing. The three models study a laminar static micro mixer with two parallel...
This is a model of the heating process in a microwave oven. The distributed heat source is computed in a stationary, frequency domain electromagnetic analysis followed. This is followed by a transient heat transfer simulation showing how...
Photonic crystal devices are periodic structures of alternating layers of materials with different refractive indices. Waveguides that are confined inside of a photonic crystal can have very sharp low-loss bends, which may enable an...
This model simulates deposition of silicon onto a wafer using a 95/5 mixture of argon and silane. The plasma chemistry consists of 19 volumetric reactions, 8 surface reactions, 11 volumetric species and 3 surface species. The plasma is...
In every system where there is conduction of electric current, and where the conductivity of the material is finite, there will be electric heating. Electric heating, also referred to as Joule heating, is in many cases an undesired...
This tutorial model demonstrates the use of a background field in an electromagnetic scattering problem. Although this example is a boat hit by a radar, this same technique can be used in any situation where an isolated object meets...
In a redox flow battery electrochemical energy is stored as redox couples in the electrolyte, which is stored in tanks outside the electrochemical cell. During operation, electrolyte is pumped through the cell and, due to the...
The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore be carefully designed to be able to withstand thermal stresses, vibrations and...
