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