Numerical Error on Natural Gas Transient Calculations
(The American Society of Mechanical Engineers (ASME), 1972)In this paper a new concept of the inertial multiplier is introduced to relax the restriction of the time increment in a computation method for natural gas transient analysis. The range of ... -
A Mathematical Analog for Determination of Porous Annular Disk Squeeze Film Behavior Including the Fluid Inertia Effect
(The American Society of Mechanical Engineers (ASME), 1972)A simple mathematical analog for determination of the squeeze film behavior between two parallel annular disks, one having a porous facing, from the already available solutions of comparable ... -
Analysis and Testing of Compressible Flow Ejectors With Variable Area Mixing Tubes
(The American Society of Mechanical Engineers (ASME), 1972)An analytical model has been developed to predict the flow behavior within axisymmetric single-nozzle ejectors employing variable-area mixing tubes. The primary flow may be supersonic or subsonic ... -
Finite-Element Analysis of Pressure Vessels
(The American Society of Mechanical Engineers (ASME), 1972)The finite-element technique has been applied in the analysis of a variety of pressure vessel problems. The example problems described in this paper suggest that the finite-element method is ... -
Impact Crater Formation at Intermediate Velocities
(The American Society of Mechanical Engineers (ASME), 1972)The influence of projectile strength on cratering was investigated for projectiles of aluminum alloys impacting semi-infinite aluminum targets over the velocity range of 1 km/sec to 5.0 km/sec. ... -
The Evaluation of the Stress Intensity Factors for Cracks Subjected to Tension, Torsion, and Flexure by an Efficient Numerical Technique
(The American Society of Mechanical Engineers (ASME), 1972)A numerical technique for the efficient computation of singular states of stress is developed and applied to several plane strain elastic problems. The method which extracts the effect of the ... -
Calibration and Application Techniques for Platinum Resistance Thermometers
(The American Society of Mechanical Engineers (ASME), 1972)The International Practical Temperature Scale has been redefined recently. It follows that the interpolating equations relating platinum resistance to temperature must be reevaluated for all platinum ... -
A Note on Grounded Thermocouple Circuits
(The American Society of Mechanical Engineers (ASME), 1972)Basic circuits involving the thermocouple as a temperature-sensing device have been described and analyzed in the literature. However, relatively little has been written on the thermocouple as ... -
The Influence of Warm Prestressing on the Brittle Fracture of Structures Containing Sharp Defects
(The American Society of Mechanical Engineers (ASME), 1972)The low temperature fracture behavior of prestressed notched bars has been studied. The fracture stress was generally below the prestress level due to the influence of reverse plastic flow at ... -
Tensile Properties of AISI Types 304 and 347 Stainless Steels at Moderate Temperatures for Section Sizes Ranging From Bars to Extremely Large Forgings
(The American Society of Mechanical Engineers (ASME), 1961)The tensile properties of AISI types 304 and 347 annealed stainless steels were investigated for the temperature range from 75 to 800 F. Several lots of materials were studied in each of ... -
Anisotropic In-Reactor Sag of Pressure Tubes
(The American Society of Mechanical Engineers (ASME), 1972)A basic solution for in-reactor sag of horizontal pressure tubes is proposed in accordance with a nonlinear anisotropic creep theorem. As an example, numerical solutions for in-reactor sag of ... -
The Effect of the Contents of the Human Red Blood Cell on Its Deformability
(The American Society of Mechanical Engineers (ASME), 1972)A review of the two main theories of red cell structure is given. One theory asserts that the cell structure is simply an elastic membrane around liquid contents, while the counter theory ... -
Turbulent Flow in Smooth and Rough Pipes
(The American Society of Mechanical Engineers (ASME), 1972)Fully developed turbulent flow in both smooth and rough-walled pipes is investigated for Reynolds numbers from 30,000 to 480,000. The values of mean velocity, root-mean-square values of the ... -
