For the understanding the behavior of the systems in EKHD, one must have a basic background in fluid mechanics, and mass, momentum, and energy conservation. These concepts can then be used to link the principles of electrokinetics to those of hydrodynamics to model the fluid motion, i.e. “electrohydrodynamics”. Once this knowledge is acquired, then the solute/analyte problem can be described. The coupling between these two domains (i.e. fluid and solute) can be effectively handled by using the spatial averaging technique (). This powerful up-scaling approach allows for the computation of analytical expressions which lead to effective, or alternative “macro,” coefficients (i.e. effective velocity and diffusivity) that represent the macroscopic behavior of the system. These coefficients can then be used to determine information relevant to practical applications such as the optimal time of separation of biomacromolecules, time for the cleaning protocol in soil remediation, among others. In this contribution, the authors will discuss the method of EKHD and the different elements associated with it; for the didactic aspects, typical assignments/exercises associated with this field of research including, problems and projects, will be included.
