Abstract EN
Electrokinetic micropumps received extra attention due to its applications in pumping of biological and chemical fluids, such as blood, DNA, and saline PBSs.
In this paper the electroosmotic flow in microchannel has been numerically investigated by developing a model from the basic governing equations (continuity, momentum, energy, and Laplace and Poison-Boltzmann equations) through a square channel with contraction of different geometries.
Utilizing the numerical analysis, a mathematical model has been built in order to study the electroosmosis-based microflow of the negatively charged messenger proteins to the negatively charged nucleus to shed more light on the electroosmotic flow behavior through microchannels with contraction.
The results obtained show a considerable effect of the zeta potential on the velocity and many parameters studied such as shapes, depth and number of contractions and channel wall material.
Adding materials with different thermal conductivity to channel wall, affect the heat distribution throughout channel length.
In particular, five wall materials typically used in Microelectromechanical systems (MEMS).
It shows that a material with low thermal conductivity works as isolation against dissipating the heat generated from Joule heating effect.
