Gas Turbine Airfoils Heat Transfer Engineer – Casting & Solidification

A Snapshot of Your Day

A Turbine Airfoils Heat Transfer Engineer for Casting & Solidification plays a pivotal role in transforming how we design and manufacture complex turbine hardware design. It involves performing detailed thermal analyses covering all three modes of heat transfer i.e. conduction, convection and radiation. A given day could involve engagement in concept generation, doing preliminary heat transfer & fluid dynamics calculations. Other days could see collaboration with interface discipline like CAD modelers to define 3D CFD/CHT simulation model, prepare boundary conditions, discussion with Casting Simulations engineers / Foundry houses, solving high fidelity CFD/CHT calculations, debugging and reviewing the results. The tasks range from design & analysis of new components, upgrade of existing components, prediction of component performance under new boundary conditions towards customer support and resolving non-conformance reports from manufacturing.

You will be collaborating in the development and validation of conventional cast, DS (directionally solidified) process modeling, core breakage prediction, and foundry process modeling capabilities. Working at the intersection of design, simulation, and manufacturing, you will focus on upstream design simulation to embed manufacturability early in the development cycle, significantly reducing defects, lead times, and costs while improving component reliability.

Job requires regular interaction with global teams hence engineer should have persuasive communication skills and cross-cultural knowledge.
