Design and Combustion CFD Engineer

Posted 1 year ago

The Role:

Advanced Innovative Engineering is looking for an experienced Design and Combustion CFD Engineer to join our team in Lichfield. You must be a professional, dynamic, involved person making critical analyses and decisions. You are expected to be part of a small management team and contribute at all times.

Reporting to the Head of Engineering, you will support AIE in designing and verifying new innovations for the Wankel Rotary Engine power units supplied to Customers within the aerospace transport and power generation markets.

As part of the close-knit team, the Design and Combustion CFD Engineer will be expected to perform the following tasks:

Design activities

  • Interpret and translate Customer and Product requirements to system and component specifications
  • Determine design options and develop appropriate verification strategies to demonstrate system/component compliance with specifications, industry standards and legislative demands
  • Ability to perform route cause analysis to determine appropriate design action required
  • Produce a system and component design which demonstrate compliance with
    • Package and clearances
    • Structural performance
    • Environmental performance
    • Delivery of whole system performance
    • Attributes – Thermal, NVH, Fuel Economy, Reliability and Power Delivery
    • Legislative demands
  • Provide Design status and Design Review documentation

1D and 3D fluid dynamics 

  • Experience with CFD Ansys suite or alternative tool kits of interest
  • Conduct flow studies to minimize DP and noise in induction systems
  • Conduct flow studies in exhaust systems to optimize performance. Experience in developing flow for acoustic performance is an interest
  • Flow analysis to optimize fan performance and efficiency
  • Flow analysis of the liquid cooling system for minimum DP and max heat rejection potential. Optimizing the engine cooling jacket for a balanced thermal environment with low DP. Flow analysis for (engine driven) coolant pump impeller and housing geometries
  • Conduct 1D analysis (or hand calculations) to determine cooling system sizing and layout. Determine requirements for Radiator sizing and DP, pump and flow rate; Fan and air flow rate and system routing and DP
  • Conduct a 3D simulation to optimize the liquid cooling system for heat rejection. This may also include ‘engine bay’ flow and thermal analysis (some applications may have a degree of engine encapsulation)
  • Conduct thermal and flow studies for air-cooled engine options. Develop cooling fin/matrix geometries appropriate for the duty and heat rejection demands
  • Conduct combustion (efficiency) related analysis for:
    • Fuel injector location and spray pattern DoE
    • Charge ‘swirl’ and mix DoE
      • Port vs direct injection studies
    • Rotor (or cylinder head) ‘pocket geometry DoE
    • Stoichiometric and Stratified fuel injection studies
  • Help drive the test and development activities correlating analytical models and verifying improvement strategies.
  • Interface with the Design Engineers to ensure robust transfer and adoption of ideas

Experience and Qualification Summary 

  • Minimum experience of 5 years in a similar analysis role
  • Master or higher Degree in a Physics or Engineering discipline
  • Knowledge of material properties appropriate for engine and ancillary systems
  • Understanding of IC engine operation and efficiency improvement drivers

Personal attributes 

  • Work well within a small team and can flex to meet Business demand
  • Team player with a ‘can-do’ attitude
  • Take responsibility and have the confidence to showcase work to internal and external Customers.
  • Disciplined, with meticulous record keeping and delivery of all activities in line with AIE processes and document retention policies
  • Clear and succinct verbal and written communication
  • Ability to research (a subject) and apply knowledge gained to analysis activities
  • Comfortable in managing priorities in line with Project, Business and Customer demand (deliver tasks to commitments)
  • Eagerness to learn and adaptive in approach.

The person: 

Self-motivated with an ability to see what needs doing and do it right. Whilst you may have to work alone, you should also be able to communicate with and participate in small group environments. Attention to detail is essential whilst planning and keeping sight of the bigger picture. You must be good at problem-solving with an ability to work to fixed deadlines.

Hours and Environment

Thirty-eight hours a week, Monday to Thursday 8.30 am to 5.30 pm (30-minute lunch) Friday 8.30 am to 12.30 pm.  

21 days plus statutory bank holidays 


The salary for this post will be commensurate with the capabilities and qualifications of the candidate. Please indicate your current salary and expectations when applying for this post.
