  4. Heating disk (High Temp.) Lower Liquid Bridge Surface Tension Higher Cooling disk (Low Temp.) Purpose of the FPEF The main purpose of FPEF is to observe and measure Marangoni convection in the liquid bridge. 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. Experiment Cell Experiment Cell FPEF • 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.
