Making use of a generalized turbulent velocity distribution for power law fluids, a Blasius type equation was derived which explicitly relates the friction factor to a generalized Reynolds number in fully developed pipe flow. Comparison of the equation with experimental data shows an agreement of ...
In order to understand the flow behavior mechanics of power-law fluids,the analytical expressions of velocity and flow rate for power-law fluids through a circular pipe with permeable wall are derived based on generalized Darcy's law and constitutive equation for power-law fluids.It is found that...

7.1 Energy, Work, and PowerThe energy equation involves energy, work, and power as well as machines that interact with flowing fluids.These topics are introduced in this section.When matter has energy, the matter can be used to do work. A fluid can have several forms of energy. Forexample...
The fully developed laminar heat transfer of modified power-law fluids in a concentric annulus with an axially moving core was analyzed taking into account the viscous dissipation of the flowing fluid. Applying the shear stress described by the modified power-law model, the energy equation including...
An incomplete regularization procedure is performed to cure the rapid divergence of the reduced two-equation model. Due to its relative simplicity the latter might be preferred in practice to the full model, at least at the initial stage of the nonlinear regime. It is also shown that the ...

To verify the foregoing analysis result, in addition, the relations between the calculated values of f and n were analyzed, when Re MR was given. The f value calculated from each equation was compared with each mean value of all the f values from the 14 equations, when each combination (...
Some industrials processes are associated with flow of non-Newtonian fluids in annular spaces. Examples are found in oil industry and food industrial processing. In some cases, gravitational forces cause internal pipe deflection and, consequently, the eccentricity changes along of axis of the annular...
