In order to get my inductance value, I rearrange the formula to get L=(2 x W)/i^2 I select the whole generator using ctrl A to get my magnetic energy density value. My problem is, when i increase the current, i from 1A to 2A to 3A (Value of current density increases), I get ...
Numerical modeling of water movement in both unsaturated soils and saturated groundwater aquifers is important for water resource management simulations. The development of efficient numerical algorithms for coupling unsaturated and saturated flow has be
Furthermore, three different approaches of magnetic force calculation in COMSOL MULTIPHYSICS are introduced showing their advantages and disadvantages. The three methods are Maxwell Stress Tensor (COMSOL default method), Maxwell Tensile Force and the method of virtual displacement. 下载...
The gas emission zone is an important parameter for the space–time effect of coal excavation and gas emission. In this paper, according to the effect of roadway excavation, a numerical model of gas emission zone based on the evolution of stress and perm
According to the actual production,in order to guarantee asphalt tank heating of the heat transfer oil could smooth return to the heat transfer oil boiler and generally appropriated heat conduction oil pressure.For the whole pipeline pressure drop was calculated,and the friction of pipe and partial...
However, COMSOL Magnetic Fields Interface uses the magnetic vector potential FEM and requires meshing both the coil and the air regions. The comparison of both codes in terms of precision, memory requirements and time of solution is presented in this paper. The parameterized model of a typical ...
COMSOL Multiphysics environmentThe operation of the cooling system of thyristor modules of a power-supply source has been analyzed, taking into account the operation modes of a PN-V1 dc plasmatron. The analysis is based on the modeling of the thermal state of the power unit, taking into ...
I am using the PDE module of COMSOL multiphysics v3.5a. the PDE, coefficient form/time-dependent analysis. now, I am solving one equation. The coefficient of my equation is a function of the COMSOL calculation results of the previous step. That is, when I am...
The simulation is performed in the Comsol Multiphysics (Acoustic Solid Interaction, Frequency Domain) software package. The frequency response of rectangular membranes 8 脳 8 脳 0.05 mm 3 in size, made of single-crystal silicon is determined. The operation of the constructed model is verified. It...
