摘要：Analysis regarding nanofluid is proved to be effective in the enhancement of heat transport features. Thus, the heat
transfer problems involving nanofluid has gained much significance in biomedical procedures, such as drug targeting
system, treatment of cancer, biotherapy, blood diagnostic and coagulation systems, and many others. Keeping this
usefulness in mind, the current attempt is presented to analyze the features of viscous dissipation in hydromagnetic
nanofluid flow through stretchable surface. Thermophoresis and Brownian diffusion phenomena are implemented to
demonstrate the transportation of nanoparticles. Modified diffusive theory is accounted to address the transportation of
heat and mass. Suitable transformations are used to get system of dimensionless governing equations. Approximate
solutions are constructed by homotopic technique. Graphical behaviors of velocity, temperature, and particles concen-
tration are described through different parameters. Skin friction is also studied explicitly. It is found that some extra
effects of Brownian and thermophoresis diffusions are appeared by implementing modified theory of fluxes. Non-
dimensional thermal relaxation time parameter causes reduction in temperature distribution while decrement concen-
tration field is observed for higher non-dimensional solutal relaxation time parameter.
