Application Projects with Turbomachinery Focus - Application Projects with Aerodynamics/Aerospace/Multiphysics Focus - Application Projects with Marine Focus (From September 2018)

NUMECA manages a collection of industrial cases that are reviewed and periodically re-run to give the best guarantees to NUMECA users about the robustness and accuracy of the products. Along this line, the objective of the internship will consist in managing several industrial projects (from the mesh to the post-treatment) running NUMECA structured & unstructured technologies. Focus of applications will be directed towards rotating machineries, including mono- and multi-stage axial and centrifugal compressors, pumps, turbines and internal cooling passages.

The candidate will manage the projects from A-Z and will thus learn how to create high-quality meshes, how to set up projects and reach fast convergence, and also make sure the simulation results are accurate by means of a suitable post-treatment. Comparison with experiments and/or literature will be part of the internship. Some of the advanced models developed inside NUMECA (including the non-linear harmonic method, the user-guided calculation of performance curves and the latest algorithmic improvements introduced to reach super-fast convergence) will be used.

The project requires a good knowledge of the flow physics, a feeling for product quality, a strong interest in industrial applications and a basic background in python programming.

Given the growing interest of designers in the FINE/Marine product (CFD software for naval architects and marine engineers), many tasks are defined to accelerate the design analysis. Hence, NUMECA has developed wizard approaches and plugins to prepare and automatically analyse the CFD simulations of the users. The objective of the internship would be to extend the current functionalities to automatically setup the simulations for resistance, seakeeping and propulsion analysis but also to ease the post processing step with various tool kits. This internship requires notions of Python programming language. Notion of CFD for hydrodynamics would be a plus.

Timing: 4-6 months

Pre-requisite: Basics of fluid CFD and hydrodynamics

Programming languages: Python                    


New Monitoring Tool Implementation

In this position you will develop for a duration of 3 to 6 months a new generation graphical tool for the monitoring of convergence history of CFD computations.

This tool should be able to plot different quantities generated by the solver, to follow its convergence.

This implies a general input file format definition that could be extended easily, and the use of a new generation graphics library for the display. 

This display might possibly be performed through a web browser, to enable remote access of the CFD computations, using state-of-the-art cloud technologies.

Best practices in CFD

NUMECA offers the great opportunity to build on the foundations of your CFD experience through the use of FINE/Open with OpenLabs. The purpose of the internship would be to define and validate the best practices for a selected application using FINE/Open with OpenLabs, but also to improve the existing documentation in support of the new best practices.

This internship requires a good knowledge in fluid dynamics, and a proficiency level in written English.

Internship related to Fluid-Structure Interaction (From September 2018)

Numeca proposes following subjects for internship/master thesis in FSI.

  • Study of wing deformation and comparison to wind tunnel data

The aeroelastic prediction workshops hold in 2012 and 2016 provided wind tunnel data on aeroelastic behavior of different wings. The aim of this subject is to use these data in order to validate aeroelastic computational methods.

Reference: 18-FSI01

Timing: 3-4 months

Pre-requisites: Basics of fluid and structure mechanics

  • Blade vibrations in axial compressors: comparison of computational methodologies

The Non-Linear Harmonic (NLH) is a powerful method to run Fluid-Structure Interaction (FSI) computations in turbomachinery. For forced response analysis, two approaches are possible with this method. On one hand, a two-way coupling FSI computation can be performed to calculate the fluid flow and the structure deformation in one computation. On the other hand, a one-way coupling FSI computation followed by a structure computation can be performed. The first computation gives the fluid load exerted on the structure. The resulting deformation of this one is calculated with the second computation. The aim of this subject is to compare both approaches in term of accuracy and efficiency.

  • Flutter wizard: development of an automatic tool for safety prediction in compressors and turbines

The flutter, a self-excited blade vibration, is one of the concerns of blade designer. If it is not properly assessed, this self-excited vibration may lead to the destruction of the machine. The evaluation of phenomenon implies multiple computations. The aim of this topic is to develop an automatic tool that will help the user to set up, launch and post-process his computations.
