The purpose of the present study is to analyse the entropy generation for the hybrid nanofluid mobilised by peristalsis. The hybrid nanoliquid is suspension of copper ( Cu ) and iron-oxide ( F e 3 O 4 ) nanoparticles in water. Impacts of magnetic field. Joule heating. https://parisnaturalfoodes.shop/product-category/soy-free-vegenaise/
