The Data Science Center for Smart Industry acts as an advanced data analytics hub for industry, aiming to improve operational efficiency, product quality, innovation and sustainability through the application of data science and analytics techniques of data in industrial processes. Contact with industries will be mediated by SENAI and operationalized through workshops and thematic meeting…
Viscoelastic fluids have many different constitutive equations that relate stress and strain. The purpose of this project is to combine numerical and asymptotic techniques to deal with the numerical instabilities that arise for the different groups of constitutive equations in their simulation of benchmark flows.Accurately simulating the behavior of viscoelastic flows has proven to be a d…
This project is concerned with the development of a numerical method for solving biaxial nematic liquid crystals subject to a strong magnetic field. The director is fixed by this field and is described by two angles. The first task is not difficult but extremely tedious: to derive the components of the stress tensor. A code will be constructed/extended from an existing code for uniaxial n…

This research project aims to address challenges in viscoelastic flow simulations, such as numerical instabilities and spurious solutions, particularly in geometries with singularities. These problems are associated with high stresses near the singularities and the High Weissenberg Number Problem (HWNP), which occurs when the Weissenberg number exceeds a critical value, generating instabi…
Left ventricular assist devices (LVADs) are an important way of improving the quality of life of patients suffering from severe heart failure while they wait for transplantation. LVADs assist the heart by pulling blood from the deficient ventricle and propelling it directly into the patient's aorta. Despite substantial advances in the development and use of LVADs in the recent decades, va…
The project to which the scholarship is linked is CeMEAI, Center for Applied Mathematical Sciences in Industry. The theme of the scholarship holder's work is related to the computational simulation of solid bodies immersed in Newtonian and non-Newtonian fluids considering regimes with low Reynolds number. The student must become familiar with the mathematical/numerical formulation and wit…
Dimensionality reduction algorithms, such as UMAP (Uniform Manifold Approximation and Projection) and t-SNE (t-distributed Stochastic Neighbor Embedding), are widely used to simplify complex datasets by reducing the number of variables while preserving essential information as much as possible. This allows for various tasks, such as data visualization or training machine learning models.H…

In this project, we propose to develop and test a new computational platform for droplet dynamics of complex fluids. In particular, we are interested in problems such as the spreading of a droplet, and the coalescence or collision between droplets. Complex fluid models will be considered, such as yield-stress or elastoviscoplastic fluids. These numerical simulations will be used alongside…
In this project, we propose to investigate some recent methodologies to treat high elasticity fluid flows. In particular, we are interested dealing with viscoelastic free surface flows considering the effects of surface tension, as for example, the die-swell extrusion and injection moulding problems. The constitutive equations used to model the rheological behavior of the fluids will be r…
The main topic of research addresses the occurrence of macrosegregation in ingot casting, a phenomena that can actuate to depletion of the product's final quality. Such formation can be described as an severe variation on macroscopic scale of chemical species that compose the alloy, and the prediction of such occurrences via computational simulations has yet to be improved. Therefore, thi…
