About R&R Consult

R&R Consult is Denmark's first consultancy dedicated exclusively to Computational Fluid Dynamics (CFD). We are a small team of specialised engineers with strong backgrounds in fluid mechanics, heat transfer, combustion, and numerical simulation.

Our size allows for close collaboration, short decision paths, and a high degree of technical influence. We value engineering insight, physical understanding, and scientific rigor over standard solutions. Discussions about modelling approaches, assumptions, and simulation results are a natural part of our daily work and an important reason why we deliver high-quality solutions to our clients.

We work on challenging engineering problems across power generation, process industries, transportation, and green technologies.

CFD is not a supporting activity at R&R Consult – it is our core business. As a CFD specialist, you will spend the majority of your time solving fluid flow, heat transfer, combustion, and multiphase flow problems rather than performing general engineering tasks.

The Position

Due to increasing demand for our CFD services within the power and process industries, we are looking for a CFD Specialist to strengthen our team.

You will work on advanced simulation projects involving:

Combustion systems

Multiphase flow

Heat transfer

Industrial process equipment

Boilers, furnaces, and thermal systems

Flow optimisation and troubleshooting

Model development, validation, and interpretation of results

Technical reporting and client interaction

The role offers significant responsibility and the opportunity to work on technically challenging projects for a wide range of industrial clients.

An M.Sc. degree in Mechanical Engineering, Energy Engineering, Chemical Engineering, Physics, or a related discipline

1–5 years of relevant CFD experience from industry, consultancy, or research

Experience with combustion simulations

Experience with multiphase flow modelling

Proficiency in Ansys Fluent

Experience with Ansys Meshing or Fluent Meshing

A strong understanding of fluid mechanics and heat transfer

Good written and spoken English

The following qualifications will be considered an advantage:

A Ph.D. degree in a relevant field

Experience from the power generation or process industries

Experience with User Defined Functions (UDFs)

Experience with transient simulations and advanced physical models

What We Offer

A highly specialised CFD-focused engineering environment

Technically challenging projects across multiple industries

Close collaboration with experienced CFD specialists

Significant influence on technical solutions and project execution

A flexible work environment based on trust and responsibility
