TNO; Rijswijk; On-site; EUR 6,700 - 7,800; Full time

Benefits offered by this job

Monthly internship allowance €615

Laptop provided

Travel expense contribution

Leave allowance (up to 8 hours per月)

Job summary

TNO invites MSc students in mechanical or aerospace engineering for an internship in Rijswijk to explore CFD–FEA predictions of thermowell vibrations. You will benchmark simulations against experimental data, review standards, and develop CFD models for selected geometries and conditions.

You will learn to predict excitation forces, validate against measurements, and assess practical limitations of CFD–FEA approaches while gaining hands-on experience in a leading research organization.

Qualifications

• MSc student in Mechanical Engineering, Aerospace Engineering or a related discipline.
• Strong interest in fluid mechanics, structural dynamics, and numerical modelling.
• Experience with CFD software (e.g., ANSYS Fluent) is preferred.
• Basic knowledge of finite element analysis and structural dynamics.
• Familiarity with Python and/or MATLAB for data processing and comparison of simulation and test results.
• You can work independently on different aspects of scientific research, including literature review and academic writing.
• You are collaborative and proactive.
• You are available to work on location in Rijswijk.

Responsibilities

• Review literature on flow‑induced vibrations of thermowells and relevant design standards (e.g., ASME PTC 19.3 TW).
• Study available experimental thermowell test data.
• Develop CFD models for selected thermowell geometries and operating conditions.
• Predict flow‑induced excitation forces and the corresponding vibration response.
• Compare numerical predictions with experimental measurements.
• Determine the accuracy and practical limitations of CFD–FEA approaches for thermowell assessments.
