Calculation Engineer – Aerodynamics and CFD

About the job

Location: Nacka/Kummelberget

At Svenska Rotor Maskiner (SRM), we are at the forefront of innovation and development in compressors for various working media such as refrigerants, biogas, industrial air, and hydrogen, with a primary focus on energy and environmental technology. Our unique rotor technology is the core of our diverse service areas, applications, and products. As we continuously design new machines for clients globally, we are welcoming a skilled calculation engineer with expertise in Aerodynamics and CFD.

What We Offer

Join a dedicated team committed to developing technical solutions for a more sustainable future and thrive in an international environment, collaborating with customers worldwide! Contribute to an ambitious company with a vast knowledge base, where you can quickly become a key player with the right mindset.

The Role

Your responsibilities will involve:

  • Conducting simulation and aero-design of centrifugal compressors and turbines.
  • Performing structural analysis of impellers and other components.
  • Providing support to our design engineers and laboratory, leveraging expertise in rotating machinery.
  • Handling general calculation tasks with CFD (Computational Fluid Dynamics)
  • Engaging in the complete chain of activities, from specification through design, prototyping, and testing.

Your Profile

You are an enthusiastic engineer or PhD with a background in mechanical engineering and a well-established expertise in CFD. Your practical experience includes working on the engineering of rotating equipment, preferably in the realm of compressors or pumps. At SRM, we utilize Ansys for CFD calculations, and we anticipate your proficiency in this or similar software. Moreover, you will actively contribute to the development of in-house calculation software for dimensioning and simulation purposes, collaborating with the rest of our R&D team. Sharing our vision of creating technical solutions for a better environmental future, you will thrive in our international work environment, engaging with customers globally.

As a pivotal player in SRM’s small yet ambitious team, you hold a key role in our journey. Your qualifications include:

  • Engineering University Master’s degree or PhD
  • Proven experience in engineering calculations, programming, and simulation
  • Preferably, previous exposure to designing/developing rotating machinery
  • Proficiency in CFD, preferably with Ansys CFX
  • Turbomachinery design skills, preferably using CFTurbo
  • Familiarity with finite element analysis, preferably using Ansys Mechanical
  • Profound knowledge in mathematics and thermodynamics
  • Knowledge in Matlab and/or other tools and languages is a natural part of the engineering work.
  • Proficiency in English, with strong communication skills in both spoken and written forms, is essential. Swedish is a major advantage.

Join SRM, where innovation meets environmental commitment!

Master Thesis Project

Svenska Rotor Maskiner (SRM)  Nacka, Stockholm County, Sweden

About SRM

Svenska Rotor Maskiner (SRM), founded in 1908, is a global high-tech company leading the innovation and development of compressors and pumps for different working media such as refrigerants, raw biogas, industrial air, and hydrogen. We offer a wide range of service areas, applications, and products, all with our unique rotor technology as its core. Our mission is to be the front-edge developer of screw compressors, expanders, and screw pumps for all different kinds of use, based on our patented rotor machine technology. Over time SRM has developed many types of technologies and applications to proceed toward high-efficiency machinery with low environmental impact. Our strategy is to maintain our position as a leading global technology innovator combined with our unique production and laboratory capacity.

About the job

Rotary screw compressors, the positive-displacement compressor type, are widely used in different industries such as refrigeration cycles, food, oil and gas, chemical process, and pharmaceutical. This type of compressor comprises a major share of the positive displacement compressor market. However, numerical simulation performed on these machines is rather limited in the literature due to the complexity of geometry and mesh generation. In recent years, the development of mesh generation in CFD commercial software paved the road towards performing numerical simulation on positive-displacement compressors.

The purpose of this master thesis is to perform numerical simulation on a screw compressor that has been designed, manufactured, and experimentally investigated at SRM. Commercial software, e.g., Ansys Forte or CFX will be used to perform numerical simulations. One of the main objectives is to establish a methodology in commercial software to perform CFD simulations and validate them against the experimental results available at SRM. This will be a continuation of the previous master’s thesis work performed at SRM. Later, the effect of different design parameters, e.g., port size, wrap angle, L/D, could be investigated.

In addition, a final presentation of the master thesis will be presented at SRM.

Your education and profile

Master’s student in mechanical engineering or similar subjects with fluid mechanics and CFD courses. Experience in CAD software, e.g., Creo Parametric, is an advantage.

Start date: 2023, week 2-5

Estimated time: 20 weeks, full time 40 h/week

Remuneration: yes

Location: Preferably at SRM (Nacka, Stockholm) or Luleå Tekniska Universitet.


Please enclose your personal letter, CV, and list of grades. Interviews will be held continuously, and the opening is valid until the announcement is withdrawn.
