Role Purpose:

• Develop and improve an in-house simulation tool for heat exchanger performance prediction, mainly using MATLAB. The tool should be modular and applicable across different heat exchanger types.
• The role will focus on predicting thermal performance and pressure drop on both media sides, using engineering principles and correlation with laboratory test data.

Objectives of this role:

• Develop a modular 1D simulation tool applicable to multiple heat exchanger products.
• Predict thermal performance, temperature changes, and pressure drop on both media sides.
• Correlate and improve simulation accuracy using laboratory test data.
• Support heat exchanger design and performance evaluation during product development.

Your responsibilities:

• Develop and maintain heat exchanger simulation tools, mainly using MATLAB Coding & Simulink.
• Build modular calculation models that can be adapted to different HEX types, such as radiators, condensers, evaporators, heater cores, CACs, and oil coolers.
• Apply thermodynamics, heat transfer, and fluid dynamics principles to develop calculation models.
• Calculate thermal performance and pressure drop for both media/fluid sides.
• Define test programs to support 1D simulation modeling, including using laboratory test data to validate and calibrate simulation results.
• Improve model accuracy and support engineering teams with performance prediction and design optimization.
• Utilize simulation and modeling tools to support design and performance predictions.

Required skills and qualifications:

• Bachelor’s degree in Mechanical Engineering, Thermal Engineering, Aerospace Engineering, Energy Engineering, Chemical Engineering or a related field.
• Master’s or PhD degree in Thermal Engineering, Heat Transfer, Fluid Dynamics, or a related field is preferred.
• Strong knowledge of heat transfer principles, fluid mechanics, and thermodynamics, pressure drop and flow resistance.
• Ability to define the engineering equation of the physical model or virtual model.
• Ability to convert engineering equations into practical calculation and simulation tools.
• Experience with other design software and tools, such as CAD and simulation software will be an advantage.
• Experience with heat exchanger development or thermal system simulation is preferred.
• Ability to work independently and manage multiple projects simultaneously.

Role Context:

• This role will help establish an in-house heat exchanger simulation capability. The engineer is expected to combine strong engineering fundamentals with programming skills to create a modular and reliable simulation tool that can be used across different heat exchanger products.
