Abstract: A test has been made of the constant turbulent Reynolds number hypothesis for a turbulent jet flow in a converging-diverging axisymmetric tube. Using the free turbulent jet as the sole source ...

Abstract: The contribution of fluid lubricated bearings to the unstable whirl and “critical speeds” of any rotor system can be expressed in terms of certain linearized coefficients. The most important ...

Abstract: A method for producing a spring of constant spring-rate versus temperature up to the range of 1000 deg F is presented by series stacking of Belleville spring washers. Several different materials ...

Abstract: In the E ? ? turbulence model an eddy-exchange coefficient is evaluated from the turbulent kinetic energy E and viscous dissipation ?. In this study we will apply the E ? ? model to the stable and neutral atmospheric ...

Abstract: The transient propagation of boiling boundary phase-change fronts during the depressurization of a subcooled liquid has been investigated for the case of thermal equilibrium without friction or ...

Abstract: This paper presents results of experimental and numerical modeling of ductile fracture and failure of elements made of S235JR steel subjected to static tension. The prediction of failure was generally based on the stress ...
