Our Work

The work developed by our group may be divided in three classes:

Over the years, we have also attended many congresses and published a number of articles in scientific journals.

ProjeCTs

  • “Formação e propriedades de emulsões na produção de óleos pesados”, Statoil, 2014/2017.

ServiCEs

We perform consulting services, among which the following should be highlighted:

  • Analysis and numerical simulations of industrial problems involving the flow of Newtonian and non-Newtonian fluids, with or without transfer of heat and mass; 

  • Complete rheological characterization of various non-Newtonian fluids, including rotational, capillary, extensional, and interfacial rheometry;

  • Measurement of other properties of liquids: density, viscosity, interfacial tension, contact angle, etc.;

    1. Calibration of volume, viscosimeters, and densimeters, with emission of RBC certificates.

Courses

GReo is one of the research groups of the Department of Mechanical Engineering of PUC-Rio(DEM). Therefore, the undergraduate and graduate courses offered by the GReo faculty members compose the respective DEM programs.

The courses offered on non-Newtonian fluid mechanics are:

  • Non-Newtonian fluid mechanics in the petroleum industry (intermediate level)

  • Non-Newtonian fluid mechanics I (graduate level)

  • Non-Newtonian fluid mechanics II (graduate level)

  • Advanced Thermodynamics (graduate level)

Furthermore, we offered, for almost a decade, an annual mini-course on the premises of GReo, on the campus of PUC-Rio da Gávea, Rio de Janeiro, lasting two days. The short course, entitled “Viscosity and Other Rheological Properties: Measurement and Applications”, was discontinued due to the COVID-19 pandemic. However, over the past year, we have reshaped and updated the course, which will now be divided into several online modules. The first module “Reologia – o que é e para que serve” will be lectured on 05/19/2021, from 5 pm to 7 pm. In this module we introduce the basic concepts of rheology and what are its industrial and day-to-day applications. At the end of this lecture, we will present the structure of the other modules and the dates of the next lectures. Click here to sign up!
