- Ideal for long term experiments and mesocosm studies on effects of biological and chemical processes and sediment transport or distribution studies.
- Continuous treatment area
- Flow driven by rotation of top plate. Counter rotation of bottom reduces cross-channel circulation. Flow speeds up to 70 cm sec-1 have been achieved in mid-water column
- Flow direction is reversible to mimic tidal direction changes
- Volume of the flume with 20-cm water depth is 700 liters. Maximum water depth is 40 cm
- 2 acrylic side panels facilitate access to water column to sample or monitor
- Temperature control (chilling) through titanium plate in the top on the water surface using a portable chiller
- Constructed of seawater resistant materials. Bottom is PVC, sidewalls are optical quality glass, top plate is PVC and titanium
The following are examples of research in the annular flumes. The research was conducted at the Department of Marine and Coastal Sciences at Rutgers University – New Brunswick prior to 2017. The flumes were moved to the Aquaculture Innovation Center in 2017.
