Incipient motion of sediments in oscillatory flows of pseudoplastic fluids: Preliminary results
(Avestia Publishing, 2017)
Preliminary results of an experimental study on the incipient motion of granular, non-cohesive particles in a laminar oscillatory flow of water and power law fluids are presented in this paper. The threshold condition is ...
Transverse and longitudinal fluid flow modelling in fractured porous media with non-matching meshes
(2021-01-01)
A new discrete fracture model is introduced to simulate the steady-state fluid flow in discontinuous porous media. The formulation uses a multi-layered approach to capture the effect of both longitudinal and transverse ...
Obtaining flow curve for viscoplastic fluids through inclined open-channel apparatus
(Springer, 2021-05-01)
Non-Newtonian fluids are commonly seen in industrial processes, such as those of the oil and mining industry, and in natural flows, like dam ruptures, landslides or mud flows. The hydrodynamic modeling of such processes/phenomena ...
Numerical simulation of isothermal upward two-phase flow in a vertical tube of annular section

Development of a low-Reynolds-number k-ω model for FENE-P fluids
(2013-01-01)
A low-Reynolds-number k-ω model for Newtonian fluids has been developed to predict drag reduction of viscoelastic fluids described by the FENE-P model. The model is an extension to viscoelastic fluids of the model for ...

Análise do escoamento de HFC-134a em tubos capilares usando o modelo de dois fluidos
(1996-03-01)
This work presents a numerical model to simulate refrigerant flow through capillary tubes, commonly used as expansion devices in refrigeration systems. The capillary tube is considered straight and horizontal. The flow is ...

Entropy variation in isothermal fluid flow considering real gas effects
(2011-01-01)
The present paper concerns on the estimative of the pressure loss and entropy variation in an isothermal fluid flow, considering real gas effects. The 1D formulation is based on the isothermal compressibility module and ...
