Cryptosteady-Flow Energy Separation
(The American Society of Mechanical Engineers (ASME), 1973)The mechanism of cryptosteady-flow energy separation is described and analyzed in its most general form, with full consideration of the effects of bearing friction or other rotor torque, and ... -
Transfer-Function Derivation and Verification for a Toric Variable-Speed Drive
(The American Society of Mechanical Engineers (ASME), 1961)Basic relationships that control the dynamic performance of toric variable-speed drives are studied. These basic toric relationships are then utilized to derive seven linear differential equations ... -
Leakage and Frictional Characteristics of Turbulent Helical Flow in Fine Clearance
(The American Society of Mechanical Engineers (ASME), 1973)The leakage and frictional characteristics of helical flow in concentric cylinders with fine clearance have been studied for the ratio of clearance to radius from 0.0006 to 0.0127 and the ratio ... -
A Simple Yet Theoretically Based Time Domain Model for Fluid Transmission Line Systems
(The American Society of Mechanical Engineers (ASME), 1973)A simple, theoretically based time domain model for the propagation of small, arbitrary signals in a finite, circular, fluid transmission line is developed. A recent simple theoretical solution ... -
Analysis of Flow Separation in an Annular Expansion—Contraction With Inner Cylinder Rotating
(The American Society of Mechanical Engineers (ASME), 1973)A three-dimensional incompressible isothermal laminar separation of a Newtonian fluid in transient and steady flow was investigated. The geometry chosen for this study was an annular expansion-contraction ... -
Alliance of the “Can-Do-ers” and the “Must-Do-ers”

Dynamic Behavior of a Simple Pneumatic Pressure Reducer
(The American Society of Mechanical Engineers (ASME), 1961)This paper presents an analysis of the dynamic behavior of a simple pneumatic pressure reducer. Both the nonlinear and the linearized problems were studied. Some experimental results also were ... -
On the Dynamics of Steam Liquid Heat Exchangers
(The American Society of Mechanical Engineers (ASME), 1961)The aim of the present work has been to present relatively simple transfer functions for steam/liquid heat exchangers, relating outlet liquid temperature to variations in, respectively, the steam ... -
Air-Hammer Instability in Pressurized-Journal Gas Bearings
(The American Society of Mechanical Engineers (ASME), 1961)A stability analysis is developed for gas journal bearings having externally pressurized pads, symmetrically spaced along the circumference. Simplifying assumptions are made and equations of flow ... -
Inertia Effects in Hydrostatic Thrust Bearings
(The American Society of Mechanical Engineers (ASME), 1961)This paper includes the predominant inertia terms in an analysis of hydrostatic thrust bearings. The influence of centripetal accelerations on the distribution of pressure is found to be ... -
Theory of Lubrication and Failure of Rolling Contacts
(The American Society of Mechanical Engineers (ASME), 1961)The fatigue life of rolling-element bearings has been the subject of numerous investigations. Most recently the influence of the lubricant on fatigue failure has been given added emphasis. This ... -
Extension of the Conducting Sheet Analogy to Externally Pressurized Gas Bearings
(The American Society of Mechanical Engineers (ASME), 1961)Incompressible, viscous flow in narrow passages bounded by parallel surfaces yields the two-dimensional Laplace equation, ∇2 P = 0. The pressure field, load capacity, and lubricant flow of ... -
A Theoretical Investigation of Pressure Depression in Externally Pressurized Gas-Lubricated Circular Thrust Bearings
(The American Society of Mechanical Engineers (ASME), 1961)A theoretical explanation of the experimentally observed depression of the pressure profile in externally pressurized gas-lubricated circular thrust bearings is presented, based on a concept new ... -
An Assessment of the Value of Theory in Predicting Gas-Bearing Performance
(The American Society of Mechanical Engineers (ASME), 1961)The object of the paper is to indicate the value of theoretical investigations of hydrodynamic finite bearings under steady-state conditions. Methods of solution of Reynolds equation by both ... -
The Effect of the Method of Compensation on Hydrostatic Bearing Stiffness
(The American Society of Mechanical Engineers (ASME), 1961)Capillary, orifice, and flow control valve compensation of hydrostatic thrust bearings is investigated theoretically with regard to the effect of these three methods of compensation on the stiffness ... -
An Improved Analytical Solution for Self-Acting, Gas-Lubricated Journal Bearings of Finite Length
(The American Society of Mechanical Engineers (ASME), 1961)An improved analytical solution designated the “linearized ph” solution is obtained for gas-lubricated journal bearings of finite length. Whereas the older first-order perturbation solution is ... -
