We’re excited to share our latest publication, “Features of the Liquid Film in Downward Vertical Air-Water Annular Flow: Downstream Flow Evolution and Disturbance Wave Parameters”, published in the International Journal of Multiphase Flow. The study developed at NUEM – Multiphase Flow Research Center / UTFPR focuses on understanding the liquid film in downward vertical air-water annular flows with a […]

We are proud to announce the publication of a paper in the Experimental Thermal and Fluid Science journal titled “Spatial Distribution of Void Fraction in the Liquid Slug in Vertical Gas-Liquid Slug Flow”. In this new study, we explore into the complex world of multiphase flows, specifically focusing on the aeration in the wake of […]

New paper from NUEM – Multiphase Flow Research Center – UTFPR: “Effect of Temperature, Pressure, and Type of Gas Injected on the Formation and Decay of Mineral Oil-Based Foams”. In three-phase gravity separators (oil-water-gas) used in primary petroleum separation process, the presence of foams can be harmful, causing various problems such as liquid carry-over, gas […]

We are proud to announce that NUEM – Multiphase Flow Research Center – UTFPR published a new paper in the Journal of the Brazilian Society of Mechanical Sciences and Engineering (https://www.linkedin.com/groups/7471069/), entitle “Experimental characterization of the dispersed bubbles in the slug of an air–water slug flow in a vertical pipe”. Our article investigates the dynamics of dispersed bubbles […]

Last week, NUEM – Multiphase Flow Research Center showcased its research at the 10th International Conference on Gas Hydrates (ICGH10) in Singapore, presenting four works and Professor Rigoberto Morales was chair in one of the flow assurance sessions. Stella Cavalli shared her experimental results in Hydrate Slurry Transport in Multiphase Slug Flow Using Hydrate-Like Particles in which experiments were […]

NUEM – Multiphase Flow Research Center attended the 8TH Thermal and Fluids Engineering Conference (Hybrid) from the American Society of Thermal and Fluids Engineers (ASTFE), presenting two works. The conference was hosted by the University of Maryland – USA, from march 26 to march 29. In this opportunity, NUEM has presented two works. The first, “Disturbance wave behavior […]

We are proud to announce that NUEM – Multiphase Flow Research Center published a new paper in the IEEE Sensors Journal, entitled “Measurement of Gas-Phase Velocities in Two-Phase Flow Using Distributed Acoustic Sensing” The paper explores a cutting-edge technology called Distributed Acoustic Sensing (DAS) that allows for highly accurate and reliable measurements in oil and […]

Our group has just published a comprehensive review of capacitive techniques for multiphase flow measurement. The paper explores the latest advances in capacitive measurement technology and provides a detailed analysis of its applications in measuring multiphase flows. Congratulations to our team for their hard work and dedication in bringing this valuable research to the scientific […]

This month NUEM attended the 19th Brazilian Congress of Thermal Sciences and Engineering (ENCIT 2022) in Bento Gonçalves, Brazil. More information about the congress:https://lnkd.in/dZHyrTHu

We are proud to announce that our group has recently published a new paper in the Experimental Thermal and Fluid Science journal, entitled “Experimental study of influence of liquid viscosity in horizontal slug flow”. The work discusses the gas-liquid two-phase slug flow in horizontal pipes with different liquid viscosities.  Detachment of elongated bubble from pipe […]
