The influence of effusion rate and rheology on lava flow dynamics and morphology: A case study from the 1971 and 1988–1990 eruptions at Villarrica and Lonquimay volcanoes, Southern Andes of Chile
(Elsevier Science, 2016-11-15)
We analyzed two historical lava flows from the Southern Andes of Chile: The lava flows from the 1971 Villarrica volcano eruption and the 1988-1990 Lonquimay volcano eruption. The 1971 lava flow has a volume of 2.3 x 10(7) ...
Orifice plate meter field performance: formulation and validation in multiphase flow conditions
(Philadelphia, 2014-01-04)
The performance of orifice plates in real-time monitoring of oil, gas and water standard flow rates was
investigated. To this end, a multi-rate test was implemented in two production wells routed individually
to a test ...

Desempenho de um sistema de irrigação por gotejamento com aplicação de Água Salina
(2015-01-01)
With the increasing search for water of good quality and maximum efficiency in application, dripping irrigation has grown in areas of family farming and smallholdings. The Brazilian northeast with its poor rainwater ...
Revisiting flow regionalization in the middle paranapanema region in the state of SÃo Paulo: The use of flow duration curves in watershedsRevisitando a regionalizaÇÃo de vazÕes na regiÃo do mÉdio paranapanema no estado de SÃo Paulo: UtilizaÇÃo de curvas de permanÊncia em microbacias hidrogrÁficas
(2020-01-01)
The scarcity of information to support decision-making in water resources management is one of the main restrictions to the adequate use of such resources. Flow regionalization, which aims to overcome the lack of measured ...
Statistical Approach for Computing Base Flow Rates in Gaged Rivers and Hydropower Effect Analysis
(Cartagena de Indias, 2023-06-27)
The calculation of base flow rates in rivers is complex since hydrogeological and hydrological
studies should be performed. The estimation of base flow rates in storm hydrograph associated to
various return periods is ...
Experimental analysis of heat transfer in packed beds with air flow
(2004-07-21)
Heat-transfer studies were carried out in a packed bed of glass beads, cooled by the wall, through which air percolated. Tube-to-particle diameter ratios (D/dp) ranged from 1.8 to 55, while the air mass flux ranged from ...

Forced flow of granular media: Breakdown of the Beverloo scaling
(Europhysics Letters, 2018-08)
The Beverloo scaling for the gravity flow of granular materials through orifices has two distinct universal features. On the one hand, the flow rate is independent of the height of the granular column. On the other hand, ...
