Friction losses in valves and fittings for power-law fluids
(Brazilian Society of Chemical Engineering, 2003-10-01)
Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous solutions of sucrose and xanthan gum, which were selected as model fluids. The rheological ...
A decomposition framework for managing inventory and distribution of fluid products by an order-based-resupply methodology
(Pergamon-Elsevier Science Ltd, 2017-11)
Fluid chemicals are usually distributed according two main methodologies; the vendor managed inventory modality and the order-based re-supply modality. In this paper, the problem of optimizing the delivery of fluids by ...
Numerical-experimental comparison of radial fans applied in pneumatic transport of agricultural fertilizer spreaders
(Univ Federal Campina Grande, 2021-01-01)
This study presents a numerical and experimental comparison of two different types of radial fans used in an agricultural fertilizer spreader at a rotation of 4000 rpm. The numerical analysis was validated through experiments ...
Kinetics and fluid dynamics for oil residue hydroconversion in commercial software
(Walter De Gruyter GmbhBerlinAlemanha, 2007)
Numerical study of the square-root conformation tensor formulation for confined and free-surface viscoelastic fluid flows
(2016-12-01)
We present a numerical study of a stabilization method for computing confined and free-surface flows of highly elastic viscoelastic fluids. In this approach, the constitutive equation based on the conformation tensor, which ...
Aminiotic fluid and intrauterine growth restriction in a gastroschisis fetal rat model
(KargerBaselSuíça, 2005)
Modeling the phase behavior of commercial biodegradable polymers and copolymer in supercritical fluids
(Elsevier Science BvAmsterdamHolanda, 2005)
A numerical study of the Kernel-conformation transformation for transient viscoelastic fluid flows
(Elsevier B.V., 2015-12-01)
This work presents a numerical application of a generic conformation tensor transformation for simulating highly elastic flows of non-Newtonian fluids typically observed in computational rheology. In the Kernel-conformation ...
