Let’s have a look at another example: The Shell and Tube Heat Exchanger from the Heat Transfer Application Library. In this case, the Thin Layer boundary condition is used to separate the water flow domain (Domain 1) from the air flow domain (Domain 2). Here, the temperature on the si...
2. The advantages of rectangular rifling are that it is the simplest structure, can be conveniently processed and has a low cost. The disadvantage is that because the inner angle of the yin line and the outer angle of the yang line are similar to right angles, the rifling shell metal is...

Send Private MessageFlag post as spam Hi everyone! I am struggling since quiet some time with a problem in joule heating in thin films. I have a resistor on a microscope glass slide and I am able to simulate Joule heating on the glass slide. I used the Electric current, Shell and the ...
In addition, the near-zero-index metamaterials13,14,15 and metacages16 pave another way to achieve transmission-type cloaking. However, the thickness of such transmission-type cloak is much larger than the incident wavelength. When cloaking an obstacle with irregular shape, the shell thickness ...
In this paper focus on, to apply thin -walled (CNG1) vessel with failure theory and to prevent stress related vessel rupture and catastrophic failure. Finite element analysis of hemispherical head and cylindrical shell position is done by using COMSOL Multiphysics.Thin Zar...
A numerical model based on the finite element method (FEM) is established in COMSOL Multiphysics software to validate the theoretical model, as shown in Fig.2. Due to the periodicity of the proposed metamaterial, only one unit cell needs to be modeled, as shown in Fig.2a. In the finite ...
The fabricated NPoM structure is schematically depicted in Fig.1c, in which the nanosphere (diameter∼100nm) is separated from the underlying gold film by a∼1nmthick CTAB (cetyltrimethylammonium bromide) shell coated on the particle. The plasmonic modes of such a nanostructure originate from...
In particular, by implementing the Finite Element Method (COMSOL) technique, we discuss the optical properties of metallic nanoshells and describe their permittivity as a function of the metallic shell thick- ness. Furthermore, the optimization study on metallic nanoshells array (size and period) ...
