Experience with Electric Drive Units (EDUs) and direct oil-cooled electric machines
Knowledge of Powertrain & transmission control valve hydraulics, clutch actuation systems, and torque converter circuits.
Familiarity with 3D CFD concepts (VOF, SPH, multi-phase churning analysis) to facilitate 1D/3D coupling.
Proven track record of correlating simulation models to physical dyno and vehicle test data
Develop and maintain high-fidelity 1D thermo-hydraulic models using GT-SUITE (GT-ISE, Flow/Cool/Hydraulics) for powertrain system
Predict and optimize parasitic power consumption (hydraulic pump power, churning/windage losses, drag torque) to maximize overall vehicle range and efficiency.
In-depth understanding of fluid mechanics, hydraulics, multiphase flow principles, thermodynamics, and heat transfer.
Demonstrated background in modeling powertrain lubrication circuits, hydraulic valve bodies, or e-motor cooling circuits.
Experience with fluid properties, low-viscosity dielectric fluids/transmission oils, oil aeration, and non-Newtonian behavior under shear/thermal stress.
Proficiency with MATLAB/Simulink or Python for data processing, scripting, and co-simulation.
Familiarity with reading and interpreting 3D CAD models in CATIA/ANSA to extract physical circuit dimensions, line lengths, and volumes.
Partner closely with physical test, dyno, and rig teams to specify instrumentation (pressure transducers, flow meters, thermocouples) and calibrate 1D simulation models against empirical data.
Collaborate with 3D CFD engineers (e.g., Star-CCM+, Ansys Fluent) to ingest boundary conditions, flow coefficients, and heat transfer coefficients into 1D lumped-parameter networks.
Leverage Design of Experiments (DOE) and optimization toolsets (e.g., modeFRONTIER, HEEDS, GT-POST optimization) to determine optimal orifice sizes, line diameters, and pump sizing
