• Build models of thermal energy storage systems, heat exchangers, and related process equipment.
• Perform mass and energy balance calculations and model heat transfer, fluid flow, and thermodynamic behavior.
• Simulate transient system behavior, including charging, discharging, and changes in operating conditions.
• Analyze simulation results, including temperature, pressure, heat flow, and energy performance.
• Validate models against engineering calculations, available data, and expected physical behavior.
• Perform sensitivity analysis and investigate the impact of different design and operating parameters.
• Use Python or MATLAB for simulation data processing, analysis, and visualization.
• Document modeling assumptions, methodology, results, and recommendations.
• Collaborate with the engineering team to improve system design and performance.

Requirements & Tech Stack

• Hands-on experience with both Modelica and OpenModelica is mandatory.
• Proficiency in Python or MATLAB for data analysis is preferred.
• Experience developing, running, debugging, and analyzing engineering simulation models.
• Understanding of dynamic and transient system modeling.

Qualifications

• Bachelor’s or Master’s degree in Chemical Engineering, Mechanical Engineering, Energy Engineering, or a related discipline.
• Strong understanding of thermodynamics, heat transfer, fluid mechanics, and mass and energy balances.
• Strong analytical, problem-solving, and technical communication skills.
• Preferred: Experience modeling thermal energy storage systems, heat exchangers, or other thermal/process equipment.
• Preferred: Familiarity with packed-bed thermal storage, charging and discharging cycles, or high-temperature heat systems.
• Preferred: Experience with Dymola, Modelica libraries, or equation-based physical system modeling.
• Preferred: Knowledge of sensitivity analysis, model validation, and techno-economic evaluation.
