CFD & Turbomachinery Engineer Required for BLDC Axial Fan Optimization Project Anyone

About the job

CFD-Based Development & Optimization of 250 mm BLDC Axial Fan
We are seeking a CFD engineer/freelancer to support the aerodynamic development and optimization of a 250 mm BLDC automotive axial fan based on existing production fan platforms and available test data.
Project Background
Available reference data includes:

380 mm production fan CAD
305 mm production fan CAD
Performance curves for 305 mm, 280 mm, and 255 mm fan variants
Target operating voltage: 12–24 V

Performance Targets

Free Flow: ≥ 3100 m³/h
Shutoff Pressure: ≥ 500 Pa
Peak Efficiency: ≥ 44%
Current: ≤ 29 A
Design Life: ≥ 40,000 hrs

Key Objective
Develop a 250 mm fan design capable of matching or exceeding benchmark performance while supporting:

30–40% material cost reduction (VAVE)
Weight reduction
Improved aerodynamic efficiency
Manufacturable design recommendations

Scope of Work
Phase 1 – Baseline Validation

CFD analysis of existing 380 mm and/or 305 mm fan designs
Mesh independence study
Generation of P-Q, efficiency, and power curves
Validation against available performance data

Phase 2 – Scaling & Aerodynamic Analysis

Non-dimensional analysis and scaling assessment
Comparison across available fan sizes
Identification of key geometric drivers

Phase 3 – 250 mm Fan Development

Performance-driven design modifications
Blade geometry optimization
Pressure, flow, efficiency, and power evaluation

Phase 4 – Final Recommendations

Phase 4 – Final Recommendations

Comparison of design concepts
Selection of preferred design
Summary report and engineering recommendations

Preferred CFD Experience

Axial fans, blowers, turbomachinery, cooling systems
ANSYS Fluent, CFX, OpenFOAM, or equivalent CFD tools
MRF and Sliding Mesh simulations
k-ω SST turbulence model
Performance curve generation and validation

Deliverables

CFD project files (ANSYS/OpenFOAM or equivalent)
Mesh and setup files
Performance curves (P-Q, Power, Efficiency)
Pressure and velocity contour plots
Optimization recommendations
Final CFD report

Additional Notes

Creo models can be provided in STEP/IGES format.
Direct support in modifying Creo-native fan geometry during optimization would be a strong advantage.
A workstation with Creo installed, OpenFOAM available (optional), and 198 GB RAM is available if collaboration or remote support is required.
