Vacancy

As a Thermal / CFD Engineer - Analyst at BlueHeart Energy, you are responsible for optimal thermal operation of the various components in the system. You do this by creating thermal designs and by simulating and testing the various components in the system. You model and optimize heat exchangers, regenerators, actuators and acoustic losses, minimizing internal thermal losses within the product.

You are familiar with Finite Element Analysis, Finite Difference and CFD simulation techniques and software, preferably COMSOL and Ansys. You perform analyses through hand calculations and using software to estimate thermal leakage rates, thermal profiles and thermal deformation in the components and in the system. You validate these analyses through bench and prototype tests. You design these components and thermal systems to control heat within the system.

You are part of the Research & Development team, consisting of four Mechanical Engineers, a Technician and a Physicist. The team is managed by the R&D Manager. The team consists of people of different nationalities, so English is the main language.

If you enjoy working with a new product which you can learn a lot from and find it challenging to do so within an organization where a lot of changes are taking place, then this is a job for you.

Working week

Thermal / CFD Engineer - Analyst

On an enjoyable working day, you have a lot of time to brainstorm new solutions to a thermal design problem. You read articles, determine possible solutions and draw up a roadmap to evaluate them.

On a less enjoyable working day, you're mostly busy reviewing other people's work, so you don't get as much of your own work done.

Firsthand experience

You are asked to estimate the heat leak between a hot component and a cold component. How do you proceed?

First, you review the CAD model with the Design Engineer to understand the existing design, including the relevant materials and interfaces. You then confirm the boundary conditions (e.g. hot-side and cold-side temperature, pressure if relevant) to be considered in the analysis. You simplify the problem and perform a hand calculation to estimate the size of the heat leak. Based on the size of the calculated heat leak and the reliability of the analysis, you determine whether a more formal FEA analysis is required. If necessary, you use the CAD model in relevant software to simulate the heat leak and compare it with the hand calculations. Finally, you summarize and share the results with the relevant Engineer.

Growth

The career growth path at Blue Heart Energy is not fixed. The company expects to grow fast in the coming years, generating opportunities for all those who are ready to assume new responsibilities. BHE supports training and courses, and sharing knowledge is very important among employees. The main advantage of the start up and scale up phase is that self-initiative is really appreciated, and you can create your own job. As Blue Heart Energy grows, you grow along with them.

Thermal / CFD Engineer - Analyst

Working at BlueHeart Energy

BlueHeart Energy was founded in 2016 to apply thermoacoustics as a technology in heat pumps and other applications as a replacement of compression technology. Thermoacoustics is a disruptive approach to generate heat and cold, with potential to revolutionize the whole industry. Over the past seven years, BHE has developed a thermoacoustic engine to power heat pumps and airco systems in residential buildings and other (industrial) applications. This so called 'Blue Heart' of a heat pump is sold to manufacturers. We are continuous improving the 'Blue Heart' with new developed and optimizations. As well we will develop different products over time. Besides this, we will set up our production facility, strengthen the relationships with our customers (OEM's and ODM's) and set up pilot projects in houses and other (industrial) applications and monitor these.
