Combustion Engineer

Job Title: Combustion Engineer

Location: Columbus, IN

Duration: Long Term

Job Summary

We are looking for a Combustion Simulation Engineer with strong experience in spark-ignited engine modeling using GT-POWER. The ideal candidate will be responsible for developing, calibrating, and validating detailed 1D GT-POWER engine models and Fast Running Models (FRM), correlating simulation results with engine test data and 3D-CFD simulations, and supporting engine performance optimization.

Key Responsibilities

• Model combustion and air-handling processes using appropriate predictive approaches for spark-ignited engines.
• Develop, calibrate, and validate 1D detailed GT-POWER engine models (DGM).
• Develop and calibrate Fast Running Models (FRM).
• Correlate simulation results from GT-POWER models with engine test data or 3D-CFD simulation data and improve model accuracy.
• Conduct GT-POWER 1D engine cycle simulations to generate boundary conditions for 3D CFD simulations.
• Apply thermodynamics, gas dynamics, and heat transfer fundamentals.
• Analyze flow behavior in intake and exhaust systems.
• Predict engine performance parameters under steady-state and transient conditions.
• Support fuel economy improvement and engine efficiency optimization.
• Evaluate turbocharger matching and air system sizing.
• Assess model robustness across operating conditions.
• Support development of validation plans for new engine configurations.
• Support optimization studies and design trade-off evaluations.
• Contribute to automation and process improvements in modeling workflows using GT-Python automation tools and/or other tools, including MATLAB and MS-Excel.
• Coordinate with internal stakeholders and external suppliers to obtain technical input and resolve model or system-level gaps.
• Work independently on assigned simulation, analysis, and reporting deliverables, ensuring technical accuracy and timely closure.
• Document modeling assumptions, calibration methods, validation results, and technical findings in technical reports.
• Communicate effectively with local and global stakeholders through professional email communication and virtual meetings to present analysis outcomes and recommendations.
• Learn new technologies and modeling approaches to enhance contributions to projects.

Required Skills (Must Have)

• Spark-ignited engine modeling using GT-POWER, including knowledge of building, calibrating, and analyzing spark-ignited engine models.
• Experience calibrating detailed GT models to reference data (experimental/CFD).
• Experience developing Fast Running GT models.
• Optimization with GT-Suite.
• MATLAB, MS-Excel, and MS-PowerPoint.
• Strong understanding of thermodynamics, gas dynamics, and heat transfer.
• Knowledge of Internal Combustion Engines (ICE).

Good to Have

• Python.
• GT-Python API.
