Facilities
Below, you can see a few examples of the materials and equipment used in the analog modeling lab. Many of these are linked to specific projects where they have been used. We use other materials and equipment not shown, but if you tune in now and then you might find that we have made some additions. We are proud to announce that in the spring of 2004, Brookfield Engineering Laboratories donated a programmable viscometer to the lab. You can read more about it by following the link below.

Viscometer
In 2004, Brookfield Engineering Laboratories donated a Brookfield Programmable RVDV-II+ PRO Digital Viscometer to the Department of Earth Sciences for use in our analog modeling laboratory. Brookfield has a large selection of rheometers and viscometers, which can be viewed here:

The DV-II+ PRO provides continuous display of viscosity (cP or mPa·s), temperature (°C or °F), shear rate, shear stress and percent torque. It has 54 selectable speeds, and we purchased Brookfield’s Wingather software which allows us to download custom programs, automate data collection, and compare data from different experiments.
The viscometer has many uses in the analog lab. For example, we can use it to explore the thermal dependence of viscosity in honey, we can conduct stress or strain-rate ramping experiments aimed at determining yield stresses, and we can perform sensitivity analysis of transitional states such as the onset of dilatancy hardening in solid-liquid suspensions (e.g., cornstarch and water).
