On the measurement of the mass flow rate of horizontal two-phase flows in the proximity of the transition lines which separates two different flow patterns
(Elsevier Sci LtdOxfordInglaterra, 2008)
Critical parameter determination of sonic flow controller diamond microtubes and micronozzles
In this article, the authors measure throughput of sonic diamond microtubes and micronozzles that can work as passive gas flow controllers and flow meters under choking conditions. The behavior of the outlet pressure through ...
Análise do escoamento de HFC-134a em tubos capilares usando o modelo de dois fluidos
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 ...
Transient flow of the oil-refrigerant mixture through the radial clearance in rolling piston compressors
Unsteady flow of oil and refrigerant gas through radial clearance in rolling piston compressors has been modeled as a heterogeneous mixture, where the properties are determined from the species conservation transport ...
Experimental analysis of heat transfer in packed beds with air flow
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 ...
Orifice plate meter field performance: formulation and validation in multiphase flow conditions
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 ...
