CFD Engineer Required – 250 mm Axial Fan Development Through CFD, DOE & Aerodynamic Optimization Anyone
About the job
We are seeking an experienced CFD Engineer to develop a high-performance 250 mm automotive axial fan using CFD-driven design methodology, DOE (Design of Experiments), and aerodynamic optimization techniques.
We currently have:
305 mm fan 3D geometry and performance curve
280 mm fan 3D geometry and performance curve
Using these benchmark designs, the objective is to develop a 250 mm fan capable of matching or exceeding the airflow, pressure, efficiency, and acoustic performance of the larger reference fans.
Project Objectives
Develop a 250 mm fan with:
Higher Airflow (CFM)
Higher Static Pressure
Improved Efficiency
Lower Power Consumption
Reduced Aerodynamic Noise (NVH)
Lower Weight
Production-oriented and manufacturable design
Scope of Work
Milestone 1 – Benchmark Study & Target Definition (USD 10)
Review 280 mm and 305 mm fan geometries
Analyze performance curves
Benchmark key aerodynamic parameters
Define performance targets for 250 mm fan
Milestone 2 – Aerodynamic Analysis & Reverse Engineering (USD 15)
Analyze blade geometry, pitch, twist, chord distribution, hub ratio, and tip region
Identify flow losses and performance limitations
Establish optimization strategy
Milestone 3 – DOE & Parametric Study (USD 15)
Define critical design variables
Perform DOE-based sensitivity assessment
Identify high-impact parameters affecting performance
Milestone 4 – Concept Generation & Aerodynamic Optimization (USD 20)
Generate multiple fan conce... read more
