Heat transfer aspects induced by natural convection in enclosures have promising utilizations and essence from theoretical as well practical prospective like in, nuclear chemical reactors, electronic devices, cooling, polymeric processes, solar power collection so forth. After viewing aforementioned extensive importance present communicatn is addressed to explain the flow attributes of Non-Newt...

Applications of multiphase flows in microchannels as chemical and biological reactors cooling systems for microelectronic devices typically present liquid slugs alternated with bubbles elongated shape, the Taylor bubbles. These occupy almost entirely cross-section channel a hemispherical front layer, lubrication film, which separates gas from tube wall. The bubble perturbs surrounding fluids ac...


 Rayleigh-Bénard's convection is a classic problem of heat transfer. Since the 1900s, studies for Newtonian fluids have been widely developed in this field and phenomena well understood. On other hand, complexity non-Newtonian behavior makes number much lower. Among behavior, shear-thinning fluid are even rarer. This work focuses on numerical study natural shear thinning, Rayleigh-Bénard ...

This thesis discusses the solution of optimal flow control problems, with an emphasis on solving optimal design problems involving blood as the fluid. The discretization of the governing equations of fluid flow is accomplished using stabilized finite element formulations. Although frequently and successfully applied, these methods depend on significant mesh refinement to establish strong consis...

Blood flow rheology is a complex phenomenon. Presently there is no universally agreed upon model to represent the viscous property of blood. However, under the general classification of non-Newtonian models that simulate blood behavior to different degrees of accuracy, there are many variants. The power law, Casson and Carreau models are popular non-Newtonian models and affect hemodynamics quan...
