One-Log Call Iterative Solution of the Colebrook Equation for Flow Friction Based on Padé Polynomials
Autor: Pavel Praks, Dejan Brkić
Publikováno v: Energies, Vol 11, Iss 7, p 1825 (2018)
The 80 year-old empirical Colebrook function ξ, widely used as an informal standard for hydraulic resistance, relates implicitly the unknown flow friction factor λ, with the known Reynolds number Re and the known relative roughness of a pipe inner

Comparative Study of Artificial Neural Networks (ANN) and Statistical Methods for Predicting the Performance of Ultrafiltration Process in the Milk Industry
Autor: Javad Sargolzaei, Naser Saghatoleslami, Sayed Mohammad Mosavi, Mohammad Khoshnoodi
Publikováno v: Iranian Journal of Chemistry & Chemical Engineering, Vol 25, Iss 2, Pp 67-76 (2006)
Milk ultrafiltration is a membrane process, which is highly complex innature. The cost effectiveness of the process depends heavily on the flux permeate and the total hydraulic resistance of the membrane. In this work, a comparative study for the pre

Review of the analytical flow model to predict the hydraulic behaviour in electrical machine
Autor: Toomas Vaimann, Anouar Belahcen, Ants Kallaste, Payam Shams Ghahfarokhi
This paper considers the analytical flow analysis for the through-flow ventilated electrical machine to predict the airflow rate in the different sections of the machine. This method can be applied to other types of air forced cooling electrical mach

Management of thermal and mechanic flow characteristics in the output channels of a turbocharger centrifugal compressor
Autor: Yu. M. Brodov, Leonid Plotnikov, B. P. Zhilkin
Publikováno v: Journal of Physics: Conference Series
It is known that the thermal and mechanical characteristics of the air flow in the output channel of a turbocharger compressor largely determine the effectiveness of the gas exchange processes quality of a piston engine. The studies were carried out

The Colebrook equation is implicitly given in respect to the unknown flow friction factor λ; λ=ζ(Re, ε∗, λ)which cannot be expressed explicitly in exact way without simplifications and use of approximate calculus. A common approach to solve it
