A Simple Method for Estimating Velocity Distributions in Swirling Flows
(The American Society of Mechanical Engineers (ASME), 1994)We describe the important structural features of swirling recirculating flows induced by a rotating boundary. A knowledge of this structure has allowed us to match the core flow to the boundary ... -
Temperature and Scale Effects Upon Cavitation and Flashing in Free and Submerged Jets
(The American Society of Mechanical Engineers (ASME), 1966)Observations of inception and desinent cavitation numbers in small submerged jets, and observations of the flashing of small, highly superheated, free jets, are presented. The observations, made ... -
A Numerical Study of Confined Turbulent Jets
(The American Society of Mechanical Engineers (ASME), 1994)A numerical investigation is reported of turbulent incompressible jets confined in two ducts, one cylindrical and the other conical with a 5 deg divergence. In each case, three Craya-Curtet ... -
Predictions of the Structure of Turbulent, Moderately Underexpanded Jets
(The American Society of Mechanical Engineers (ASME), 1994)A mathematical model capable of predicting the structure of turbulent, underexpanded jets is described. The model is based on solutions of the fluid flow equations obtained using a second-order ... -

Parameter Representation of Low-Temperature Yield Behavior of Body-Centered Cubic Transition Metals
(The American Society of Mechanical Engineers (ASME), 1966)In the low-temperature range, the engineering yield strength of polycrystalline bcc metals can change by a factor of 10 or more with serious consequences appearing in the form of catastrophic ... -
Discussion: “Cyclic Operation of Pressure Piping With γ Heating” (Merckx, K. R., 1960, ASME J. Basic Eng., 82, pp. 447–451)

Some Mechanical Properties of Uranium-10 Weight Percent Molybdenum Alloy Under Dynamic Tension Loads
(The American Society of Mechanical Engineers (ASME), 1966)Dynamic tensile tests were conducted on uranium-10 weight percent molybdenum alloy in as-cast and wrought conditions. Carbon content was varied from 71 to 800 ppm. Heat-treatment was also varied. ... -
Design and Analysis of Commercial Pressure Vessels to 500,000 Psi
(The American Society of Mechanical Engineers (ASME), 1966)On the basis of the finiteness of the flow strength of structural materials, the pressures permitted by current methods of pressure vessel design are limited. In this paper the analysis of a ... -
Some Experimental Results Concerning Spread in the Rolling of Lead
(The American Society of Mechanical Engineers (ASME), 1966)Lead bars of various height-to-width ratio have been rolled down in a model rolling mill to reductions of as great as 60 percent between rolls designated as smooth, partially rough, and rough. ... -
The Bauschinger Effect in a High-Strength Steel
(The American Society of Mechanical Engineers (ASME), 1966)The object of this work was to evaluate quantitatively the Bauschinger effect in a 4330 modified steel as a function of strength level and structure as derived from variations in heat-treatment. ... -
Stability Conditions for a Class of Distributed-Parameter Systems
(The American Society of Mechanical Engineers (ASME), 1966)The purpose of this paper is to obtain stability conditions for a class of nonlinear distributed-parameter systems by using a generalization of Liapunov’s direct method. Sufficient conditions for ... -
An Extension of the Describing-Function Method
(The American Society of Mechanical Engineers (ASME), 1966)The use of the describing-function method has been generally limited to systems with nonlinearities which can be combined in a block diagram of a feedback control system which is represented ... -
Identification of Systems Described by Partial Differential Equations
(The American Society of Mechanical Engineers (ASME), 1966)A method is given for the identification of distributed parameter systems. Normal operating records or experimental data may be used. The method involves the determination of arbitrary parameters ... -
A Nonlinear Filter for Independent Gain and Phase (With Applications)
(The American Society of Mechanical Engineers (ASME), 1966)Compensation of control systems by means of linear filters is a basic and well-known art. However, the limitations of linear compensation are also well known. In particular, the interdependence ... -
A Study of Fluid Squeeze-Film Damping
(The American Society of Mechanical Engineers (ASME), 1966)The fluid squeeze-film produced by relative axial or tilting motion of two closely spaced plates provides viscous damping action over certain ranges of operation. When gas is the working fluid, ... -
Minimization of Solar Radiation Pressure Effects for Gravity-Gradient Stabilized Satellites
(The American Society of Mechanical Engineers (ASME), 1966)The considerations necessary for minimization of solar radiation pressure effects for gravity-gradient stabilized vehicles are presented here. Owing to the rather weak restoring forces available ... -
