Numerical simulation of electroosmotic flow in a rectangular microchannel with use of magnetic and electric fields

Pumping fluid is one of the crucial parts any microfluidic system. Using electric and magnetic fields as a substitute for moving can have many advantages. In this study hydrodynamic heat transfer characteristics electroosmotic flow under influence lateral transverse field, are studied numerically. Results indicate that dimensionless parameters such Hartmann number, intensity pressure gradient parameter aspect ratio an important role in controlling flow. It be implied enhancement leads to decrease critical dependency reduced from 44% 7% S=0.5 S=50 two gradients Ω=1 Ω=20. addition, reduction microchannel section increment number specified field. At end, thermal analysis being done by consideration effects on Nusselt number.
