A Snapshot of Your Day

As an Aerodynamic turbine designer, you are responsible for the design and optimization of our turbine airfoils & diffusor to maximize turbine performance. The tasks range from design & analysis of new airfoil design, upgrade of existing airfoil/components, prediction of airfoil row/stage component performance under new boundary conditions towards customer support and resolving non-conformance reports from manufacturing. To do so, you will apply a variety of different tools and 1D, 2D and 3D methods. You will make decisions based on simplified low fidelity approaches if possible or run a 3D CFD or multi-disciplinary optimization to find solutions for complex design tasks, or anything in between. You will be part of a global team and collaborate closely with colleagues from adjacent disciplines i.e. heat transfer, mechanical integrity, and manufacturing to develop a design that is a balanced compromise between project requirements for performance, lifetime and costs.

The tasks can include coming up with conceptual design, failure mode evaluation & root cause analysis, detailed aerodynamics analysis, report writing and defending key technical reviews. Deep knowledge of fluid dynamics, aerodynamics, and thermodynamics fundamentals are essential. Basic understanding of Aeroelasticity/Aeromechanics, Heat Transfer and appreciation for the structural integrity field are desirable. In addition to this, aerodynamics engineer needs to support manufacturing support qualification and field-testing aspects, (post final design review) for validation of the product. It is expected to provide technical advice about the suitability of developed design and its application across multiple gas turbine frames. Job requires regular interaction with global teams hence engineer should have persuasive communication skills and cross-cultural knowledge.

How You'll Make an Impact (Gas Services)

• Turbomachinery aerodynamics calculations for axial gas turbine design, focusing on airfoils & exhaust diffusor. Have in-depth knowledge in numerical simulation (1D, 2D and 3D) of compressible flows in turbomachines.
• In-depth knowledge in any commercial or in-house Quasi 3D CFD, throughflow and blade to blade tool/solver.
• Independently able to create CFD setup by translating various assumptions & design requirements into the numerical model. Experience in CFX, Star CCM+.
• 2D/3D Aerodynamics CFD calculations to create turbine performance maps for the turbine hot flow path.
• Turbine mean-line design, cascade design and analysis.
• Knowledge on how to evolve a Turbine Airfoil design & perform optimization while satisfying Design for Manufacturability.
• Able to understand physics, apply relevant assumptions, interpret results & perform basic hand calculations in Fluid mechanics, Aerodynamics & Heat Transfer discipline.
• Able to understand the product function, design requirements and design principles.
• Problem solving skills, self-learning capabilities.
• Be a point of contact, speaking partner and provide expertise regarding hot gas path aerodynamics related topics in a project.
• Working with project lead to understanding the project requirements, finding solutions to design challenges, and delivering results within agreed timeline & quality.

What You Bring

• Mechanical/Aerospace engineer with a Master’s degree / M. Tech in Mechanical / Aerospace engineering (major - Aerodynamics, Fluid dynamics).
• Strong understanding of Fluid dynamics, Turbomachinery aerodynamics and Computational Fluid Dynamics.
• Minimum 5 years of relevant experience in Aerodynamics design & analysis of axial turbomachinery, Airfoil profile design, Design for Manufacturability.
• Good understanding of CFD codes like CFX, StarCCM+, meshing tools like AutoGrid, Optimization tools like HEEDS etc.
