Abstract
This study conducts a comprehensive analysis of the role of polymers in boundary layer flow and heat transfer of non-Newtonian fluids over a shrinking surfaces, considering viscous dissipation effects. Governing equations are transformed into a similar form, and numerical solutions reveal the impact of polymers, mass suction, and viscous dissipation on drag and heat transfer near the surface. Visual representations highlight the findings, notably identifying dual solutions within a specific range of the mass suction parameter. Polymer concentration, viscous dissipation, fluid properties, and stretching/shrinking surface parameter significantly affect heat transfer rates and skin friction. The presence of polymers over shrinking surface shows opposite effects on drag coefficient in both the branches. The exploration of dual solutions and their impact on drag coefficient and heat transfer is emphasized as the novel aspect of this work.
期刊介绍:
The journal includes papers in the following areas:
– Simple organic liquids and mixtures
– Ionic liquids
– Surfactant solutions (including micelles and vesicles) and liquid interfaces
– Colloidal solutions and nanoparticles
– Thermotropic and lyotropic liquid crystals
– Ferrofluids
– Water, aqueous solutions and other hydrogen-bonded liquids
– Lubricants, polymer solutions and melts
– Molten metals and salts
– Phase transitions and critical phenomena in liquids and confined fluids
– Self assembly in complex liquids.– Biomolecules in solution
The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include:
– Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.)
– Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.)
– Light scattering (Rayleigh, Brillouin, PCS, etc.)
– Dielectric relaxation
– X-ray and neutron scattering and diffraction.
Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
