Thermal Fluid Engineer – Cooling Air System & Clearance Design

A Snapshot of Your Day

As a Thermal Fluid Engineer, you’ll use advanced fluid dynamics and heat transfer analysis to shape the performance and reliability of large gas turbines. You’ll design and analyze internal cooling air systems, secondary air systems, and component clearances using advanced simulation tools, while collaborating with a global engineering team on both new product development and service initiatives. Your work will directly influence turbine efficiency, durability, and continuous improvement across the fleet.

- 60% Thermal-Fluid System Modeling & Simulation

- Develop and maintain complex models to describe the cooling air supply for hot gas-path components in gas turbines.

- Simulate transient heating and thermal expansion of the entire turbine to determine optimal assembly gaps and clearances.

- Utilize a combination of in-house and commercial simulation software to perform fluid dynamics and heat transfer analyses.

- Analyze and interpret simulation results to validate models against empirical data and derive design-relevant conclusions.

- 40% Design, Analysis & Improvement

- Contribute to the conceptual and detailed design of gas turbines, specifically focusing on the secondary air system and clearance design.

- Evaluate operational data, prototype findings, and fleet feedback to support design improvements and enhance product reliability.

- Participate in risk assessments, such as Failure Mode and Effects Analysis (FMEA), for new and modified designs.

- Collaborate with cross-functional teams including project management, component engineering, and manufacturing to ensure design feasibility and integration.
