Our new Thermo-Haake rheometer even has a microscope attached so that we can study rheological properties to the evolution of microstructure. Part of our interest in this topic is motivated by trying to understand the effects of implications of bubbles and crystals in magmas and lavas (see recent papers by Rust and Manga (2002) J. NonNewt. Fluid Mech., Rust and Manga (2002) J. Colloid Int. Sci., Saar et al. (2001) Earth Planet. Sci. Lett., Hoover et al. (2001) J. Volc. Geotherm. Res., Manga and Loewenberg (2001) J. Volc. Geotherm. Res.) We (actually Alison Rust with the help of Dave Senkovich) have also built our own couette rheometer to study the rheology of bubbles fluids. The diameter of the outer cylinder was 29 cm. Why so big? we are interested in the effects of bubble deformation. To get large deformations it helps to have large bubbles. Large bubbles requires a large gap. See the 2002 paper by Rust and Manga in the Journal of nonNewtonian Fluid Mechanics for more details.
