Two Fluid

A new iterative approach is outlined for multidimensional computational analysis of two fluid flow. Parametric surveys are described to illustrate that the method rationally predicts separation of two fluid flows under gravitational and centrifugal influences. A comparison is made between behavior computed by the method, and results reported in an experimental study of air and water flowing in elbows and pipes.

The Stability

The membrane stress field in a spinning disk induced by a stationary circumferential friction force is first derived in the form of an infinite series. It is then shown, both by analysis and numerical computation, that this membrane stress field has no effect on the stability of transverse vibration of the spinning disk.

Edge Notch

Structures containing non-sharp defects exhibit a higher apparent resistance to cleavage fracture than sharp cracks. This paper presents a numerical and experimental study of the cleavage fracture behaviour of single edge notch bend SE(B) specimens with cracks and notches with varying notch root radii. The experimental study demonstrates the increasing resistance to fracture that occurs with increasing notch root radius. This is complemented by a numerical study that quantifies the elastic-plastic stress field ahead of the crack or notch tip. The results of the numerical and experimental studies are used together to show that the cleavage initiation sites, identified using scanning electron microscopy, are located close to the peak tensile stress field occurring ahead of the notch. This implies that a tensile stress criterion is the main controlling factor for cleavage fracture in the notched specimens analysed.
