This paper presents the two dimensional numerical modeling of the coupling electromagnetic-hydrodynamic phenomena in a conduction MHD pump using the Finite volume Method. Magnetohydrodynamic problems are, thus, interdisciplinary and coupled, since the effect of the velocity field appears in the magnetic transport equations, and the interaction between the electric current and the magnetic field...

A double coil magnetorheological (MR) valve with an outer annular resistance gap was designed and prototyped. The finite element modeling and analysis of double coil MR valve were carried out using ANSYS/ Emag software, and the optimal magnetic field distribution and magnetic flux density of the double coil MR valve were achieved. The mechanism of the pressure drop was studied by building a mat...

A 3D mathematical model of orthodontic archwire with rectangular curve is established. Simplified 3D solid model of orthodontic archwire bending robot, which is consistent of bending die, support structure and archwire are established by Creo software, then the simplified model of bending die is put into ANSYS Workbench. Material parameters the contact condition and boundary conditions are set ...

Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior in the glass transition regime. COMSOL Multiphysics software 4.3b can simulate the stress relaxation with the WLF (WilliamsLandel-Ferry) shift function, but no structural relaxation. In this study we developed a framew...

The basic concept of dynamic characteristics of spindle is introduced. The first ten order vibration mode and natural frequency of shaft are obtained by modal analysis and harmonic response analysis using software ANSYS. The deformation trend of spindle under resonance state is analysed and the contrast between theory and simulation critical speed is done. The frequency response curve of spindl...

A fixture is designed and built to hold, support and locate every component to ensure that each is drilled or machined with accuracy and manufactured individually. A fixture can be designed for a particular job. A brake spider includes a spider body with a central opening and a slot for receiving a camshaft and bracket assembly. The brake spider is attached to axle housing via the central openi...

Homework problems are useful in that they provide practice for mastering the technical steps in the application of a software package. However, when a complex industrial problem is to be solved, a significant amount of modeling must first be performed before the software can be utilized to good effect. Modeling is believed by many to be the essence of engineering. It requires the attainment of ...

The paper presents a boundary condition independent transient thermal network model generated by means of model order reduction methods. The order reduction is performed with MOR for ANSYS which is based on the Krylov subspace method via the Arnoldi algorithm. Subsystems such as a semiconductor device and the printed circuit board are modeled with ANSYS, separately. Then, these models are used ...

The recent advent of microelectromechanical systems (MEMS) or micro-devices has generated excitement in many diverse fields. In the area of micro-fluidics liquid pumps are highly desirable for fluid transport and atomization. A recent and popular example of this is the inkjet, which self-aspirates ink from a reservoir and then transports it to a chamber for expulsion as a single droplet during ...
