Continuous liquid transport in micro-channels was achieved using evaporation and capillary forces. Flow velocity increased with an applied air stream, reaching up to 2.25 mm/s for aqueous solutions.

Area of Science:

  • Fluid Dynamics
  • Microfluidics
  • Transport Phenomena

Background:

  • Micro-scale fluid transport is crucial for various applications.
  • Traditional methods often require external pumps or pressure gradients.
  • Evaporation-driven and capillary-driven flows offer passive transport mechanisms.

Purpose of the Study:

  • To report a continuous liquid transport process in micro-channels.
  • To investigate the influence of evaporation and capillary forces on flow generation.
  • To explore methods for enhancing liquid transport velocity.

Main Methods:

  • Fabrication of micro-channels (110 µm wide, 28 µm deep, 4/10 cm long) in a two-glass-layer device.
  • Generation of liquid flow using evaporation at the channel end and capillary forces.

  • Measurement of liquid transport velocity for aqueous solutions.
  • Application of an air stream over the evaporation zone to study its effect.

    • Main Results:

    • Continuous liquid transport was successfully demonstrated in the micro-channels.
    • Observed liquid transport velocities reached up to 2.25 mm/s for aqueous solutions.
    • Guiding an air stream over the evaporation zone significantly increased the flow velocity.

    Conclusions:

    • Evaporation and capillary forces provide an effective means for continuous liquid transport in micro-channels.
    • External air flow can be utilized to enhance passive microfluidic transport.
    • This method holds potential for applications requiring controlled, pump-free liquid handling at the microscale.
