Numerical analysis of melting heat transfer in stratified Casson nanofluid flow over an inclined wedge for energy-efficient thermal systems

Purpose Given the diverse applications of nanoparticles, blood transport and stratified flow in medical and industrial domains, this study was conducted. Design/methodology/approach Nonlinear thermal stratification is used to capture realistic, high-gradient thermal environments...

Weak solutions for a generalized Katugampola fractional Langevin inclusion with boundary condition

We investigate weak solutions of a fractional Langevin inclusion subject to a nonlocal boundary condition and involving the generalized Katugampola-Caputo derivative. The problem is posed in a real Banach space and the multivalued nonlinearity is treated through Pettis-integrable...

2D-unsteady chaotic flows for mixing two different non-Newtonian fluids: optimization and flow control

Mixing of non-Newtonian fluids has been widely studied, yet numerical investigations of the simultaneous mixing of two different shear-thinning fluids inside chaotic mixers remain limited. In this work, we numerically investigate, for the first time, the mixing of two shear-thinn...
