Abstract: Helium buffered floating-ring seals used in cryogenic turbopumps are sujbect to large temperature variations, shaft centrifugal growth, and dynamic shaft excursions. To prevent dangerous contact ...

Abstract: Use of the Type 1 Extreme Value Distribution of Maxima to design engineering problems is reviewed. Results of a Monte Carlo study of the statistical behavior of the distribution parameter ...

Abstract: Flow distribution in the lateral branches of dividing, combining, reverse, and parallel flow manifold systems is studied both analytically and experimentally. Predictions for the flow rates and ...

Abstract: The one-dimensional equations of flow in the elastic arteries are hyperbolic and admit nonlinear, wavelike solutions for the mean velocity, U, and the pressure, P. Neglecting dissipation, the ...

Abstract: A study of laminar pulsating flow through a 45 degree bevel pipe orifice was performed using finite-difference approximations to the governing stream function and vorticity transport equations. ...

Abstract: Partial flow problems in circular pipes are commonly solved using standard hydraulic element charts or nomograms. These methods are tedious, monotonous, and subject to errors. The widespread availability of the desktop ...

Abstract: Civil engineers recognize the need to better address the potential consequences of infrastructure systems on social equity. However, the challenge has been translating social equity concerns into metrics that are usable ...

Abstract: This paper develops a kinematic model to predict the axial migration of the rollers relative to the nut in the planetary roller screw mechanism (PRSM). This axial migration is an undesirable ...

Abstract: Three-dimensional flows through canine femoral bifurcation models were predicted under physiological flow conditions by solving numerically the time-dependent threedimensional Navier-stokes equations. ...

Abstract: This paper presents Chevron Oil Field Research Company’s operating experience using the sonic nozzle as a proving device for measuring natural gas flows in field tests. The nozzle reference ...
