Application Projects with Turbomachinery Focus - Application Projects with Aerodynamics/Aerospace/Multiphysics Focus - Application Projects with Marine Focus 

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.

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.

DEVELOPMENT OF MODELS FOR THE POST-PROCESSING OF NOX FORMATION

The emissions of NOx contribute to the formation of acid rain and the production of smog. In the design and optimization of low-NOx combustion devices (engines, gas turbines, furnaces,...) it is important to account for the current restrictive regulations on the emission of pollutants. Since the NOx formation is a slow process, computational methods assuming fast chemistry (like the equilibrium approach) cannot be used for accurate predictions. As the NOx concentrations are very low compared to the other combustion products and the formation of the NOx does consequently not affect the flow field, the NOx formation can be determined by post-processing the results of a reactive simulation. FINE/Open contains a module for the post-processing of the NOx formation. As this module only considers the thermal formation of NOx (Zeldovich mechanism), in the current project this module will be extended to also incorporate the prompt formation of NO (Fenimore), the formation of NO due to the oxidation of nitrogen-containing compounds in the fuel, and the reduction of NO due to reactions with hydrocarbons. Validation will be conducted by simulating both elementary test flames and industrial applications. The work will be carried out in collaboration with TU/Eindhoven (TU/e), NL.

Supervisor: Jan E. Anker, Luigi Romagnosi, Jeroen van Oijen (TU/e)

Timing: 4-6 months (Internship or MSc project)

Prerequisites: Knowledge in fluid mechanics, numerical methods, and CFD

Programming languages: C++

Reference: 19-03

How to apply? Please send your CV, cover letter and ranking/transcripts at job@numeca.be. With your application please provide a list of two references and one letter of recommendation of your current/school university.

VALIDATION OF CHEMICHAL REACTION MECHANISMS FOR INDUSTRIAL USE

For combustion modelling NUMECA offers a variety of tabulated chemistry models (equilibrium, flamelet, FGM, …) since they are reliable and computationally efficient. The combustion tables are generated using TabGen/Chemistry, which is NUMECA's table generation tool and is based on TU Eindhoven's 1D chemistry solver Chem1d. Unless equilibrium tables are generated, chemical mechanisms are needed to generate the combustion tables. In the combustion module of FINE/Open with OpenLabs there are some preprocessed chemical mechanisms offered for use by NUMECA's clients. To extend the database of chemical reaction mechanisms, new detailed reaction mechanisms for common fuels will be preprocessed and validated for industrial use. The testing process will consist of generating a combustion table based on the new mechanism, run elementary and industrial test cases with the combustion table, and compare the results with available reference data. If a chemical mechanism yields good results, the mechanisms and its range of validity will be documented, and eventually added to the database of TabGen/Chemistry. The work will be carried out in collaboration with TU/Eindhoven (TU/e), NL.

VALIDATION OF COMBUSTION MODELS FOR COMPRESSIBLE FLOW

For combustion modelling NUMECA offers a variety of tabulated chemistry models (equilibrium, flamelet, FGM, …) as they are reliable and computationally efficient. Standard implementations of these combustion models assumes low Mach number flow. To be able to use a tabulated chemistry model for high-speed flows, NUMECA has recently extended the Flamelet Generated Manifolds (FGM) method so that this model can be used for the simulation of reacting flows at arbitrary Mach numbers. For increasing the confidence and ensuring the quality of the implementation, additional elementary and industrial test case will be carried out. As supplementary industrial test cases, one rocket-chamber and one coupled combustor-NGV simulation should be carried out. In addition, to compare the computational results of the test cases with measurement data, scripts in Python and documentation should be written, so that the test cases can be included in our system for automated verification and validation tests.
