Summary
Eyring-model fluids (EMF) show potential for controlling mixing in electrophoretic cells. Their ability to handle high Joule heat generation makes them suitable carriers for enhanced dispersion phenomena.
Area of Science:
- Fluid dynamics
- Electrophoresis
- Heat transfer
Background:
- Electrophoretic cells rely on carrier fluids for mixing and dispersion.
- Joule heating significantly impacts fluid behavior and temperature profiles within these cells.
- Understanding non-Newtonian fluid dynamics is crucial for optimizing electrophoretic processes.
Purpose of the Study:
- To investigate the effects of Joule heating on Eyring-model fluids (EMF) in an electrophoretic cell.
- To derive analytical expressions for temperature and velocity profiles of EMF.
- To compare the hydrodynamic behavior of EMF with other fluid models.
Main Methods:
- Sequential coupling of heat and momentum transfer equations.
- Derivation of analytical expressions for temperature and velocity.
- Analysis of fluid behavior in a batch electrophoretic cell.
Main Results:
- Analytical expressions for temperature and velocity profiles of EMF were derived.
- The study elucidated the hydrodynamic behavior of EMF under Joule heating.
- EMF demonstrated effective mixing capabilities, especially with high Joule heat generation.
Conclusions:
- Eyring-model fluids are promising carriers for electrophoretic applications due to their thermal properties.
- EMF can be utilized to control mixing and dispersion within electrophoretic cells.
- The findings provide a basis for comparing EMF with Newtonian, power-law, and CEF model fluids.
