Test System for the characterisation of the air flow velocity profile of components (e.g. tubes, filters).The air flow velocities between 1-40 m/s and turbulences in the outlet of flowed through units under test can be measured.
Through this, a good position for flow velocity measuring devices (for example MAFs) in flowed through parts (for example motor inlet filters) can be found easier, taking into consideration a range of air flow rates. The data created by the flow scanner can also be used to check models for flow simulation.
Applications
development of filter housings and air-ducting elements in general
comparison of models for flow simulation with measured values
Flow field uniformity analysis of air filters and filter assemblies;
Flow behavior evaluation of engine intake systems and intake filter housings;
Optimization of installation positions for air velocity and mass air flow sensors (e.g. MAF sensors);
R&D validation of ventilation equipment, air supply modules, and air handling units;
Comparison and verification of CFD simulation results with measured data;
Performance assessment of new air duct designs, guide vanes, and flow straightening structures.
Standards
The system can be used in accordance with the following standards and technical references:
(1) GB/T 1236 Industrial Fans – Performance Testing Methods
(2) GB/T 10178 Industrial Fans – Field Performance Testing
(3) ASHRAE Handbook – Fundamentals (Air Flow Measurement and Testing Sections)
