The interplay of plasticity and elasticity in elastoviscoplastic flows in wavy channels

Mohamed S. Abdelgawad, Simon J. Haward, Amy Q. Shen +1

Elastoviscoplastic (EVP) fluids, which exhibit both solid-like and liquid-like behavior depending on the applied stress, are critical in industrial processes involving complex geom…
