Unlike the conventional electroosmotic flow (EOF) driven by direct current and alternating electric fields, this study investigates pulse EOF of Newtonian fluids through a parallel plate microchannel actuated fields. Specifically, pulses considered encompass triangular half-sinusoidal waves. By applying Laplace transform method residual theorem, analytical solutions for velocity volumetric rate associated with these two waves are derived, respectively. The influence width a¯ electrokinetic K on is further considered, while as function time t¯ examined separately. A comparison rates related to under varying parameters also conducted. research findings indicate that irrespective wave, broader results in prolonged period increased amplitude profile. Elevating yields higher near-wall velocities, negligible effect near-center velocities. It noteworthy regardless width, exceeds during first half-cycle, situation reverses second half-cycle. varies periodically time, initially surging rapidly before gradually stabilizing at constant level. More interestingly, independent linked wave consistently surpass those wave. For any corresponding grow widths, especially prominent intervals half-cycles within complete cycle. These have important implications improving design optimization microfluidic devices engineering biomedical applications utilizing EOF.
