About the assignment

A key passive heat transfer technique in tubular heat exchangers is distorting a laminar flow by creating turbulence with the use of turbulator inserts within tubular heat exchangers. Based on

pressure drop and heat transfer correlations obtained by experiment, a calculation can be made of the effectiveness of the device and to determine optimal turbulator geometry with the given dimensions and conditions of the heat exchanger.

The goal of this assignment is to develop a calculation tool which is based on Reynolds, Prandtl and Nusselt correlations obtained from experiments and literature. The most suitable programming language for the calculation tool will be determined during the graduation assignment.

Foreseen activities are:

  • Literature study regarding important parameters of convective heat transfer within tubular heat exchangers. Validation of correlations obtained in experiment.
  • Literature study on possibilities calculation tool (examples) and selection of relevant options for our application
  • Proposal calculation tool design and defining a test plan for investigating performance and reliability of the tool
  • Building and validation of the calculation tool.

We are looking for a Master graduation student with:

  • ¬†Experience with one or more of the following programming languages: JavaScript, Visual Basic .NET, C#, C++, Python, C, Java;
  • Affinity and/or experience with Thermodynamics, Fluid mechanics, Heat transfer and Heat exchangers

We offer:

  • An interesting graduation assignment at which you can realize genuine added value
  • A good internship allowance
  • An open and flexible working environment
