Packed Bed Reactor Experiment (PBRE)
Managed By: NASA
Implementation Partner: ZIN Technologies
- Hardware is designed to operate in the MSG glovebox.
- Experiment assembly provides two phase flow through a clear, polycarbonate column filled with spherical, glass packing. The gas is ISS provided nitrogen and the liquid phase is pure water doped with orthohthalaldehyde (OPA) to prevent biological growth. Diagnostics include pressure transducers , digital imaging and Electrical Capacitance Tomography (ECT), a new technology developed for this experiment.
- Imaging is performed with two Prosilica GX cameras capable of taking images of 1024 x 1024 pixels at 100 fps.
- Polycarbonate column will be outfitted with 5 Kistler 4045A2V64 pressure transducers capable of reading pressures with a plus or minus 0.02 psi accuracy.
- Experiment data will be streamed to and recorded by dual Nitro 1 terabyte solid state hard drives that have
been tested for radiation susceptibility.
- ECT technology is underdevelopment by ZIN technologies through a subcontract with Tech4, an Ohio
- State University start up.
