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 ...

The non-linear sewing lemma III: Stability and generic properties
(Walter de Gruyter GMBH, 2020)
Solutions of Rough Differential Equations (RDE) may be defined as paths whose increments are close to an approximation of the associated flow. They are constructed through a discrete scheme using a non-linear sewing lemma. ...
Geometrical and kinematic properties of interfacial waves in stratified oil-water flow in inclined pipe
(ELSEVIER SCIENCE INCNEW YORK, 2012)
The stratified oil-water flow pattern is common in the petroleum industry, especially in offshore directional wells and pipelines. Previous studies have shown that the phenomenon of flow pattern transition in stratified ...
Roll-Waves Mathematical Model as a Risk-Assessment Tool: Case Study of Acquabona Catchment
(Asce-amer Soc Civil Engineers, 2018-12-01)
In an attempt to develop risk-assessment engineering tools, a method is presented that involves the application of a simplified model that represents periodic permanent roll waves in Herschel-Bulkley laminar fluid flows. ...
Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...
Analytical model for interfacial waves in vertical core flow
(Elsevier Science BvAmsterdamHolanda, 2006)
Free-surface laminar flow of a Herschel-Bulkley fluid over an inclined porous bed
(Elsevier B.V., 2019-10-01)
The current work presents a mathematical solution for the flow of a Herschel-Bulkley fluid over a porous bed. To obtain the velocity profile, a dimensional analysis is firstly conducted for the Darcian-like flow, showing ...
A model for thermal gradient and heat flow in central Chile: The role of thermal properties
(Elsevier Ltd, 2019)
The aim of this work is to quantify variations in heat flow and thermal gradient patterns at the latitude of central Chile and to evaluate the role of thermal properties of macro-geological units within the lithosphere. ...
