The paper expands the work by Kinnear and Weston[1] on squeeze film bearing design to the general case and compares the revised methodology with classical bearing design[2,3,4] and hybrid bearing design[5]. The analysis, which employs a partial differentiation of the Poisseuille and Hagen-Poiseuille bearing flow equations, enables a mathematical model for the bearing squeeze film to be develope...

Squeeze-film effects of perforated plates for small amplitude vibration are analyzed through modified Reynolds equation (MRE). The analytical analysis reckons in most important influential factors: compressibility of the air, border effects, and the resistance caused by vertical air flow passing through perforated holes. It is found that consideration of air compressibility is necessary for hig...

In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

Squeeze film effects between two concentric cylinders are common and important in many mechanical systems. The models for cylindrical squeeze force vibrating system with have not been well understood. In this paper, we model a starting from the simplification of full Navier–Stokes equations then get an expression force. We study influence harmonic exciting on spring damped vibrator effect by es...

The present work deals with analyses of the effects of bearing curvature and non-Newtonian characteristics on the load capacity of an exponential rectangular squeeze film bearing using Bingham fluids as lubricants. Bingham fluids are characterized by an yield value and hence the formation of a “rigid” core in the region between the plates is justified. The flow is confined to the region between...

We present a simple three-class model in the Kaleckian tradition to investigate the implications of a dominant managerial class class for the dynamics of demand and distribution. Managers are hired by capitalists to supervise workers, but supervision results in surplus extraction and wage inequality. The adjustment of capacity utilization to accommodate goods market disequilibrium produces two ...

In the first asymmetric heavy ion collision studied by the FOPI collaboration the reaction Ca on Au was investigated both in normal and inverse kinematics, at a projectile energy of 1.5A GeV [1]. The experiment shows the suitability of the FOPI detector system in measuring asymmetric collisions and the physics potential of this reaction type in the SIS energy regime. The physics observables rep...
