Stability Analysis on Rotor Systems Supported by Self-acting Tilting-pad Gas Bearings with Frequency Effects
bearing-rotor system tilting-pad bearing logarithm attenuation rate
2011/8/4
The recent research on stability of gas bearing-rotor systems still mostly adopts the same method as in oil-lubricated bearing-rotor systems. The dynamic coefficients of gas bearings in the case that ...
Numerical Analysis of a Spiralgroove Drygas Seal Considering Microscale Effects
numerical analysis Reynolds equation
2011/8/4
A drygas seal system is a noncontact seal technology that is widely used in different industrial applications. Spiralgroove drygas seal utilizes fluid dynamic pressure effects to realize the seal and ...
Effects of Residual Stresses Caused by Different Types of Loading on Silent Chain Strength
Silent chain elasto-plastic residual stress finite element
2009/10/14
Engagement and disengagement of a chain with sprocket teeth results in fatigue loading, particularly when one of the sprockets is small, and the chordal action contributes to problem. Silent chain lin...
Viscous Heating Effects in Viscoelastic Flow between Rotating Parallel-Disks
Polymeric (Viscoelastic) fluid Parallel-Disks Rheometry Nonisothermal
2009/10/12
Viscoelastic flow between two rotating parallel-disks (plates) is studied. First the current state of the art is discussed and the limitations resulting from the simple flow assumptions are reported. ...

Magnetic feld Thermal radiation Viscous dissipation Forced convection
2009/10/10
Magnetohydrodynamic (MHD) forced convection heat transfer from radiate surfaces in the presence of a uniform transverse magnetic eld, with conductive fluid suction or injection from a porous plate is...
The Effects of Wall Properties on Peristaltic Transport of a Dusty Fluid
Peristaltic transport Wall properties Dusty fluid
2009/9/30
The interaction between peristaltic transport of a dusty fluid (Saffman’s model) in a 2-dimensional uniform channel and the elasticity of the channel’s flexible walls was studied under long wavelength...
