Modeling of water spraying of field releases of hydrogen fluoride

The effectiveness of water sprays to absorb HF releases has been recently demonstrated by extended laboratory and field tests. In this paper computer simulations are presented of the Hawk, Nevada Test Site, series of field tests, along with parametric studies of several cases which have not been studied in the field. The model used in these simulations, HFSPRAY, treats the gas-phase as an Eulerean fluid whereas the spray is described according to the Lagrangian approach by a finite number of dr… more

Nuclear shell model calculations with non-local interactions

It is becoming clearer with time that non-locality of the nucleon-nucleon interaction can play a significant role in nuclear properties. In this talk we review evidence for such non-locality. Then, using a Gaussian interaction, we discuss the effect of non-locality on two body matrix elements in the nuclear shell model. Finally, we mention some applications. For example, non-locality leads to faster convergence of off-diagonal matrix elements.

Anistotropic yielding of rocks at high temperatures and pressures

The anisotropic deformation of foliated and linealed rocks has been investigated, primarily to predict the mechanical response of rocks surrounding buried magma chambers to the stress fields generated by deep drilling. The principal application in this regard has been to evaluate, the scientific feasibility of extracting geothermal energy from buried magma chambers. Our approach has been to perform triaxial extension and compression tests at temperatures and pressures representative of the bore… more
