A new 3-D Fokker-Planck code, CQL(parallel-to), which solves the Fokker-Planck equations with two velocity coordinates and one spatial coordinate parallel to the magnetic field lines B/B, has been developed. This code enables us to model the parallel trans ...
The two-region model was developed originally to describe nonsorbing chemical transport in soils with dead-end pores based on the concept of mobile and immobile regions in the soil. It has been shown that the model can simulate solute transport in soils wi ...
We show that in He II a counterflow without any local center-of-mass motion cannot be maintained, except for special symmetries of the flow field (e.g., plane axial or spherical symmetry) and for second-sound waves with small amplitudes. Our considerations ...
Measurements of toroidal and poloidal rotation of the TCA plasma with Alfven wave heating and different levels of gas feed are reported. The temporal evolution of the rotation was inferred from intrinsic spectral lines of C V and C III, and, using injected ...
A novel bench-scale calorimeter, which is based on a heat-flux principle and modified to accommodate biol. reactions, was evaluated for detg. the heat evolution rate of an aerobic culture of the yeast Kluyveromyces fragilis grown on lactose. The instantane ...
This paper shows that the instabilities which are observed in cells cannot be explained by supposing that the mechanical and electromagnetic fields are independent of the space variable x3 corresponding to the length of the cell. For a model which is infin ...
Experimental flow analysis of hydraulic machines is of prime importance for improving the design of such a unit. Moreover, computational fluid dynamics codes need an experimental data reference in order to check their ability to simulate the main flow feat ...

The fluid flow through a tube with an oscillating elliptical cross-section was analyzed in order to understand better the effects of lateral deformation and movement on flow patterns in large and medium-sized blood vessels. Time-dependent elliptical deform ...
The feasibility of Thomson scattering to determine the beam velocity in a gyrotron has been analyzed and preliminary experiments to implement such a system on our 100 GHz quasi-optical gyrotron are reported. Although the project had to be abandoned due to ...
An experimental study of flow in a Francis hydraulic turbine, especially designed for the GAMM Workshop, has been carried out. In order to provide a data base for the validation and comparison of computational fluid dynamics codes, a Francis turbine mode! ...
