Density waves

Figure 2. Wavepacket dynamics of the H + H H2 + H scattering reaction, shown as snapshots of the density (wave packet amplitude squard) at various times, The coordinates, in au, are described in Figure la, and the wavepacket is initially moving to describe the H atom approaching the H2 molecule. The density has been integrated over the angular coordinate, The PES is plotted for the collinear interaction geometry, 0 180, ...

The pressure spike introduces a disruption in the flow. Depending on the local conditions, the excess pressure inside the bubble may overcome the inertia of the incoming liquid and the pressure in the inlet manifold, and cause a reverse flow of varying intensity depending on the local conditions. There are two ways to reduce the flow instabilities reduce the local liquid superheat at the ONB and introduce a pressure drop element at the entrance of each channel, Kandlikar (2006). Kakac and Bon (2008) reported that density-wave oscillations were observed also in conventional size channels. Introduction of additional pressure drop at the inlet (small diameter orifices were employed for this purpose) stabilized the system. 

The UHF solution appears when the hopping integral t becomes small and leads to a spin density wave. The localization of the MOs leads to a and b atom centered orbitals, localized around odd and even labelled atoms respectively.

Simple dynamic instability. Single dynamic instability involves the propagation of disturbances, which in two phase flow is itself a very complicated phenomenon. Disturbances are transported by two kinds of waves pressure (or acoustic) waves, and void (or density) waves. In any real system, both kinds of waves are present and interact but their velocities differ in general by one or two orders of...

The following parametric effects on density wave instability are summarized, as these effects have been often observed in the most common type of two-phase flow instability (Boure et al., 1973) ...
