Multiphase immersed boundary numerical simulation of industrial mixing devices - 2026_IDR_DMAT_7

Position: Research appointment (pre-doc) Institute: Polytechnic of Milano
Posted on: 25/05/2026 Deadline: 22/06/2026

Scientific-Disciplinary Group

01/MATH-05 - Numerical Analysis

Description

The research activity will focus on the development of a numerical solver for two-phase flows in industrial mixing devices. In particular, the currently available immersed-boundary multiphase solver in the OpenFOAM library will be extended to non-isothermal problems. A systematic optimization of the solver’s numerical parameters will also be carried out to improve efficiency, enhance stability, and reduce computational costs, with validation against industrial benchmark cases. The model limitations under critical operating conditions (e.g., partial filling regimes) will be analyzed, exploring alternative approaches (including the extension to a compressible fluid model) to mitigate their impact. Finally, calibration and validation of wall slip conditions will be performed using experimental data to improve the predictive accuracy of the model for industrial polymeric materials.
