Abstract: This work examines electro-osmotic peristaltic transport of Casson fluid in a two-dimensional channel under the influence of thermal radiation, entropy generation, and ciliary motion. The governing equations account for electrokinetic forces, non-Newtonian rheology, and cilia-induced wall motion, with thermal radiation modelled via the Rosseland approximation. Using long wavelength and low Reynolds number assumptions, analytical and numerical solutions are obtained for velocity, temperature, and entropy profiles. The effects of electro-osmotic strength, Casson parameter, thermal radiation, Brinkman number, and ciliary activity are analysed, showing enhanced transport and thermal regulation, with notable impacts on velocity distribution and entropy generation. This comprehensive study provides insights into optimising microscale fluid transport in biomedical and engineering.

Keywords: electro-osmotic; cilia wave; peristaltic flow; thermal radiation; Casson fluid; entropy generation.
