Popis: The enhancement of energy by introducing nanoparticles is a hot topic in the present century, due to industrial and technological applications. Therefore, current article investigates the peristaltic flow of $$\mathrm{Ag}{-}\mathrm{H}_2\mathrm{O}$$ nanofluid with entropy generation through a uniform channel. Hall and Radiation effects are incorporated. Two-phase formulation for nanofluid is employed. Long-wavelength approximation is used in the mathematical modelling. Built-in numerical solver NDSolve is utilized. Numerical results of the coupled equations are sketched for several quantities of interest. Outcomes of the study reveals that entropy significantly reduces for large values of Hall parameter, whereas opposite behaviour is noted for velocity. Increase in the values of radiation parameter reduces the velocity, temperature, and entropy generation. Increase in Bejan number is observed for enhancement in Brinkman number. Rate of heat transfer at walls increases when heat source parameter is increased. Additionally, comparison of different nanoparticles is also furnished through tables.
