[Draft for a Painting (St. Cyprien)].

This symbolic study of "St.Cyprien" concentration camp life done while Nussbaum was interned there in France. It is inscribed "Entwurf zu einem Gemälde" (Study for a painting) at lower left corner. It shows a group of men huddled around a globe or hunched in isolation against a desolate background of barren land and barbed wire. The drawing is one of the most artistically powerful and technically perfect in the collection.

Rheological flow from a die and painting on a moving solid wall

Die swell is an important, phenomenon. in polymer processing, and is explained usually by rheological properties of the fluid. Because of the nonuniform of temperature distribution on the free surface of the liquid jet, the thermo capillary convection driven by surface tension gradient exists. The rheological fluid flowing out of a die and painting on a moving solid wall is studied by the numerical finite element method of a two-dimensional and unsteady model in the present paper, and both the rheological effect of a non-Newtonian fluid and the thermocapillary effect are considered. The results show that both,effects; will enlarge the cross-section of the fluid jet, and the rheological effect of non-Newtonian fluid dominates the process in general.
