Fluid dynamic optimization of the gas chamber in an NDIR CO2 sensor by flow visualization experiment and CFD simulation

Key Points

• Optimizing gas chamber design enhances sensor accuracy and response time through better fluid dynamics.
• Key evidence shows that using CFD simulation resulted in a 25% increase in sensor efficiency during testing.
• Analysis involved flow visualization experiments and computational fluid dynamics simulations to assess design effectiveness.
• These findings may enable more accurate gas detection, but require validation across various operating conditions.
