Thermohydrodynamic Characteristics of Journal Bearings Running under Turbulent Condition
A thermohydrodynamic (THD) analysis of turbulent flow in journal bearings is presented based on the computational fluid dynamic (CFD) techniques. The bearing has infinite length and operates under incompressible and steady conditions. In this analysis, the numerical solution of Navier-Stokes equations with the equations governing the kinetic energy of turbulence and the dissipation rate, couple...
متن کاملClosure to “Discussion of ‘Factors of Safety for Richardson Extrapolation’ ” (2011, ASME J. Fluids Eng., 133, p. 115501)
The Technical Brief by Roache [1] presents ten items of discussion of our factor of safety (FS) method for solution verification [2]. Our responses are listed below item-by-item using the same numbering as Roache. The nomenclature mostly follows our own and not Roache’s such as pRE for the order of accuracy calculated using the Richardson Extrapolation as opposed to the observed order of conver...
متن کاملA Study of the Thermal Characteristics of the Leading Edge Groove and Conventional Tilting Pad Journal Bearings
Kingsbury, Inc., Philadelphia, PA 19154 In this paper dealing with the tilting pad journal bearing, experim'ental results are presented which show that, at higher shaft speeds, the leading-edge-groove (LEG) design has significantly lower operating temperatures to those of the conventional design of tilting pad journal bearing. Subsequent theoretical analysis has shown that this reduction in pad...
متن کاملProposal Performance Measurement of ATSP Coating and Bulk PEEK Faced Tilting - Pad Thrust Bearings
Background: Under severe operating conditions, such as lubricant contamination, elevated temperatures and high unit loads, the hydrodynamic (HD) lubrication condition in a HD bearing may degrade and be reduced to mixed and boundary lubrication conditions, which traditional pad bearing materials (Babbitt metal) are not able to sustain. For example, Electrical Submersible Pump (ESP) systems are r...
متن کاملDesign Of Journal Bearings In Reciprocating Compressors
Journal bearings in hermetic reciprocating compressors are analyzed experimentally as well as numerically. The motor current and the load applied to the bearing are measured to obtain the performance curve of the journal bearing, from which the critical Sommerfeld number is derived. In the numerical analysis, the Reynolds equation and equilibrium equations of the journal center are solved simul...
