Study of Anisothermal Short Journal Bearings With non-Newtonian Lubricants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The equations describing the flow of simple non-Newtonian oils in short journal bearings are solved approximately for low eccentricity ratios and small viscosity variations with temperature. An ...
Response of Viscoelastic Fluids in Dynamically Loaded Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic response of polymer fluids to small sinusoidal shearing motions may be characterized by their relaxation spectra. Recent experiments show that great changes can be induced in the ...
Increase of Bearing Loads Due to Large Normal Stress Differences in Viscoelastic Lubricants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The calculation of increased bearing capacity due to large viscoelastic or normal stress effects is carried out exactly for plane slider bearings with a second-order fluid lubricant.
Complex Variable Analysis for Stepped Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is shown how simple series solutions can be found for the bearing characteristics of stepped thrust bearings with curved steps. Loads are shown to be higher than with straight steps. The ...
Theory of a Thermal Fluxmeter in a Shear Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is known from some recent experiments that a thin, electrically conducting plate on an electrically insulating base gives a heat transfer rate to a laminar shear flow about twice that ...
A Short-Bearing Solution for Pressure Distribution in a non-Newtonian Lubricant
Publisher: The American Society of Mechanical Engineers (ASME)
A Burgers-Type Model of Turbulent Decay in a Non-Newtonian Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To study the effects of the high elongational viscosity on the free (“grid-generated”) turbulence of polymer solutions, a Burgers-type model equation is proposed and formed by replacing the ...
Effects of Combined Shearing and Stretching in Viscoelastic Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is argued theoretically that in normal bearing and squeeze film geometries, when using a nonlinear Maxwell constitutive relation, that elongation and normal stress effects are of minor importance.
