Specifically, a two-equation dynamical system is utilized to replicate the time evolution of experimental parallel velocity values of a bull spermatozoa’s head during circular swimming. The differential system accurately models the sperm’s planar movement in three different scenarios. Additionally, the time marching of the differential system employs a least-squares analysis on a system with a larger amount of sampled data and fewer data points, demonstrating its reliability in approximating the actual pattern. Furthermore, a linearized model of the system is explored near its equilibrium points. The study also demonstrates the application of this straightforward system when dominant external viscous forces arise from swimming in a nanofluid. Finally, the paper discusses the optimal modes with the highest velocity magnitude when oscillating forces come into play.</span></div>}, number={1}, journal={Journal of Advanced Research in Micro and Nano Engineering}, author={Shervin Sharafatmandjoor and C‎. ‎S‎. ‎Nor Azwadi}, year={2022}, month={May}, pages={1–8} }
