Experiment CellExperiment Cell

Purpose of the FPEF

Marangoni convection is driven by the difference of the liquid surface tension, and surface tension is higher at low temperature part than at high temperature part.

FPEF is used in combination with Experiment Cell, and provides following capabilities.

Form the liquid bridge and generate Marangoni convection. Observe and/or Measure Marangoni convection.

Accomodate Experiment Cell. Observe/Measure Marangoni convection in three ways.

Control and measure temperature of Experiment Cell. Provide resources to Experiment Cell.

Provide telescience operation and sequential control automation.

Experiment Cell

FPEF Major Components

Experiment Cell contains experiment sample.

Experiment Cell has the heating disk and the cooling disk, forms liquid

bridge, and creates temperature gradient between the disks.

The design of Experiment Cell depends on the experiment purpose.

- has unique observation/measurement system. - has unique disk size. e.g. 30, 50 mm in diameter - has unique sample. e.g. Silicone oil, small particles

Crew member assemble/disassemble Experiment Cell.

Crew exchange Experiment Cell/sample cassette.
