Enhanced Heat Transfer in Methanol-Based Magnetic Hybrid Nanofluids: Influence of Thermal Radiation, Viscous Heating, and Velocity Slip on Stretchable Cylindrical Surfaces

Hybrid nanofluids have become important for improving heat transfer in various engineering fields, especially in rotating cylinders, energy conversion systems, and efficient heat exchangers. Motivated by the need to elevate heat transfer efficacy, the present research explores th...

Transient hydromagnetic couple‐stress flow over an infinite vertical cylinder: A unified numerical exploration of thermal radiation and Arrhenius activation energy kinetics

Abstract Couple‐stress fluids characterize the rheological behaviour of microstructure suspensions such as polymeric melts, lubricants, biological fluids, and colloidal mixtures. These fluids exhibit particle‐scale rotations and size‐dependent characteristics that significantly a...
