International travel report by Dr. Jefferson Luís Melo de Almeida Gomes

Report on the activities performed and results obtained by Dr. Jefferson Gomes in the Project “Computational Modeling for Applications in Engineering and Environment”, Institutional Internationalization Program (CAPES-PRINT) 41/2017, Process No. 88887.583882/2020-00 in the year 2022.

This report includes the activities performed by Dr. Jefferson Gomes during his stay (07/19 – 08/17, 2022) at the Instituto Politécnico da Universidade do Rio de Janeiro (IPRJ/UERJ). The activities were carried out at the facilities of the Laboratório de Experimentação e Simulação Numérica em Transferência de Calor e Massa (LEMA) as part of the project “Computational Modeling for Applications in Engineering and Environment”.

During this period, the following activities were developed at UERJ (Maracanã and Nova Friburgo Campuses), Instituto Federal Fluminense (Campos dos Goitacazes Campus, IFF/CG) and Universidade Federal do Rio de Janeiro (UFRJ, COPPE-Nuclear):

1. Guest speaker;
2. Participation in scientific events;
3. Technical meetings with professors and companies;
4. Technical meetings with post-doctoral and graduate students;
5. Courses taught.

1.Guest speaker

During the visit period, two lectures were held, whose target audience were teachers and students from graduate programs in computational modeling. The lectures lasted 45-50 minutes with additional time for questions and discussion.

I) IPRJ/UERJ (21/07): “Self-Adaptive Computational Methods for Multi-Physics Problems”, where the development of computational methods (based on hybrid finite element method and finite volumes) for nuclear energy (thermohydraulics and severe accidents in reactors, reservoirs (oil-gas and geothermal energy) and pollutant dispersion in urban areas were addressed;
II) IFF/CG (27/07): “Strategies for Modeling and Simulation of Multi-Physics Problems Applied to the Environment” where the application of computational methods and order reduction methods to the simulation of multiphase fluids in porous media (contaminants in aquifers) were addressed.

2.Participation in scientific events

Participation in the scientific meeting (19-20/7) on “Transport of Micro-Plastics in Oceans and Estuaries”. The meeting was part of an international scientific collaboration project (CAPES/FCT, FAPER/FCT and CAPES-PRINT) involving:

  • Universidade do Estado do Rio de Janeiro (UERJ):
I) Post-graduation program in Computational Modeling of the Polytechnic Institute (IPRJ/UERJ);

II) Physical Oceanography and Meteorology Department of the Oceanography College (Ocean/UERJ);
III) Department of Chemical Processes of the Chemistry Institute (IQ/UERJ).

  • Post-Graduate Program in Modeling and Technology for Environment Applied to Water Resources (IFF/CG);
  • Universidade de Lisboa: Center for Environment and Sea Science and Technology (MARETEC, “Marine Environment and Technology);
  • Universidade dos Açores: Instituto do Mar (IMAR).

This meeting aimed to disseminate progress and partnerships among the participants allocated in Brazil. The following were present: Professors Antônio José da Silva Neto (IPRJ/UERJ), Gleyci Aparecida Oliveira Mozer (Ocean/UERJ), Alexandre Macedo Fernandes (Ocean/UERJ), Alessandro Mendonça Filippo (Ocean/UERJ), Jader Lugon Jr (IFF/CG), Manildo Marcião de Oliveria (IFF/CG), David de Andrade Costa (IFF/CG), Victor Barbosa Saraiva (IFF/CG), Dr Kelly Cristine da Silveira (IPRJ/UERJ), Mr. Nikolas Souza (IFF/CG, doctoral student) e Mr. Allyson Tavares (IFF/CG, doctoral student). These researchers discussed methods and methodologies (models, numerical simulations, data collection and analysis of samples and data) used in the activities so far. There were also opportunities to visit the Oceanographic Vessel Professor Luiz Carlos at Marina da Glória. During the two day meeting, Dr Gomes had opportunities to discuss strategies for modeling and simulation with some of the researchers, particularly with Professors Gleyce Mozer, Jader Lugon Jr and Manildo Oliveria.

3.Technical meetings with professors and companies

  • Meetings with Professor Joaquim Teixeira de Assis (UERJ/IPRJ) to discuss a proposal of collaboration in the co-supervision of a PhD student (IPRJ) in concrete characterization;
  • Meetings with Professor João Flávio Vasconcellos (UERJ/IPRJ) to discuss collaboration in a research project on moving meshes (finite volume method) applied to the optimization of Sterling cycle engines;
  • Meeting with Professor Su Jian from the Department of Nuclear Engineering at UFRJ/COPPE for cooperation in mentoring PhD student (University of Aberdeen) on a project on modeling and numerical simulation of flux of critical thermal energy in nuclear reactors, and in particular on heterogeneous nucleation mechanisms;
  • Meeting with Dr Carlos Eduardo Fontes from ESSS on collaboration on a project on numerical simulation of multiphase flows in submerged pipelines (hydrocarbon exploration/production).

4.Technical meetings with post-doctoral and graduate students

  • Meeting with Dr Josiele Teixeira (IPRJ/UERJ) to collaborate on a project to determine petrological properties (g., absolute permeability) using inverse problem techniques coupled with high order numerical models;
  • Meeting with Dr. Kelly Silveira (IPRJ/UERJ) to discuss a project on membranes, involving synthesis and simulation of flow through membranes. Development of models for hydrate formation and transport were also discussed;
  • Meeting with Dr. Roseana Alves (IPRJ/UERJ) to discuss collaboration on a project on pollutant transport in urban areas and the application of inverse problem algorithms to determine the origin of the release;
  • Meetings with doctoral students Guido Carvalho (IPRJ/UERJ) and Douglas Correa (IPRJ/UERJ) to present their research projects on the development of a numerical model for the advection-diffusion-reaction (ADR) problem, with a high-order diffusion term (diffusion with retention). The model couples the solution of the direct and inverse problems.

5.Courses taught

The following mini-courses were taught at IPRJ/UERJ:

  • Introduction to Computational fluid Dynamics (6 hours);
  • Energy Transition – Alternatives to Fossil Energy (8 hours):

I) Geothermal Energy: Technology Transfer from Oil and Gas Exploration Sector (High Pressure and Temperature Fields) to Renewables;
