On the accuracy of two-fluid model predictions for a particular gas-solid riser flow
(ELSEVIER SCIENCE INC, 2010)
Literature presents a huge number of different simulations of gas-solid flows in risers applying two-fluid modeling. In spite of that, the related quantitative accuracy issue remains mostly untouched. This state of affairs ...
Numerical analysis of refrigerant flow along non-adiabatic capillary tubes using a two-fluid model
(Pergamon-Elsevier B.V. Ltd, 2009-02-01)
This work presents a numerical model to simulate steady state refrigerant now along capillary tube-suction line heat exchangers. commonly used in small refrigeration systems. The flow along the straight and horizontal ...
A two-fluid model for refrigerant flow through adiabatic capillary tubes
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2014-01-01)
This work presents a numerical model to simulate refrigerant flow through capillary tubes, commonly used as expansion devices in refrigeration systems. The flow is divided in a single-phase region, where the refrigerant ...
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 ...
Modeling and optimization of supercritical fluid processes
(Elsevier Science, 2008-01-20)
In this work, we discuss recent advances on thermodynamic modeling, process simulation and optimization of supercritical extraction and fractionation processes. The increasing availability of experimental data, as well as ...
A new pool boiling heat transfer correlation for wetting dielectric fluids on metal foams
(Elsevier, 2021-02-19)
Porous structures, as metal foams, can enhance the heat transfer performance. For a safe industrial application, a predictive model for both heat transfer coefficient and maximum heat flux is required. But, there is no ...
A two-phase solver for complex fluids: Studies of the Weissenberg effect
(Elsevier B.V., 2016-09-01)
In this work a new two-phase solver is presented and described, with a particular interest in the solution of highly elastic flows of viscoelastic fluids. The proposed code is based on a combination of classical Volume-of-Fluid ...
Spectrum of shallow water gravity waves generated by confined two-dimensional turbulence
(American Physical Society, 2018)
We apply Lighthill's theory of aeroacoustic sound generation to shallow water gravity waves generated by spatially confined two-dimensional turbulence. We show that the frequency spectrum of surface waves at large distances ...
Coupling scales for modelling heavy metal vaporization from municipal solid waste incineration in a fluid bed by CFD
(Pergamon-Elsevier Science Ltd, 2015-09)
Municipal Solid Waste Incineration (MSWI) in fluidized bed is a very interesting technology mainly due to high combustion efficiency, great flexibility for treating several types of waste fuels and reduction in pollutants ...
