The spatial spectrum of intensity fluctuations due to a concentrated layer of turbulence is derived from the parabolic wave equation. The spectrum of refra... VH Rumsey - 《Radio Science》 被引量: 29发表: 2016年 Power-Law Entropy Corrected Ricci Dark Energy and Dynamics of Scalar Fields Motivat...
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 ...

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 ...
This paper reports on the numerical computation of the turbulent flow of power-law fluids in smooth circular tubes. The turbulence is represented by means of a modified version of an existing two-equation turbulence model. Numerical results are presented for the fully-developed friction factor and ...
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...
In this paper we have discussed the flow of power law fluids between two parallel plates with uniform suction and injection under constant pressure gradient. We have obtained equation of velocity profiles and also we have calculated the ... M Singh,PN Rai - 《Acta Ciencia Indica》 被引量: ...

Minimization of this "free power" functional with respect to the microscopic one-body current yields a closed equation of motion. In the equilibrium limit the theory recovers the standard variational principle of DFT. The adiabatic dynamical density functional theory is obtained when approximating the ...
An analysis is presented for skin friction of power law fluids in turbulent flow over a flat plate. A momentum balance is combined with a logarithmic velocity profile and the resulting equation is integrated. Skin friction is shown to be a function of non-Newtonian Reynolds number and power law...
