20.500.12556/DKUM-27907 On new approach to rheological modeling of an electrostatic ash and water - quadratic law In the paper a new rheological model for an electrostatic ash and water mixture is proposed. The fundamental equation of the rheological model was used to determine the relationship between the shear stress and the shear rate as well as the equation of a velocity profile for the flow through a straight pipe. Experimental results obtained from a capillary viscometer were used as the basis to determine the parameters for the proposed model by the non-linear regression analysis. With the Quadratic law a numerical analysis of a mixture flow through a capillary pipe with the finite volume method was performed. The derived equations for the velocity profile, shear stress and shear rate were validated through a comparison of numerically obtained and theoretical results. Finally, the compariosn between the Quadratic and the Power law is presented. fluid mechanics non-Newtonian fluids mixture of electrofilter ash and water flow in pipes capillary pipes rheological model velocity profile shear stress finite volume method numerical analysis quadratic law power law mehanika fluidov mehanika fluidov nenewtonski fluid zmes elektrofilterskega pepela in vode tok v ceveh tok v kapilarni cevi reološki model hitrostni profil metoda končnih volumnov numerična analiza kvadratni model potenčni zakon mehanika fluidov true false false Angleški jezik Angleški jezik Neznano 2012-06-01 13:09:20 2012-06-01 13:09:20 2022-04-15 03:45:55 2021-04-11 03:28:25 2002 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 532.135:532.584:532.542 8334102 URN:SI:UM:DK:P9KNIS5I http://www.rheofuture.de/papers2002/030902_si_01.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=37254 Fakulteta za strojništvo 0 0 0
