AI Technical Summary

Technical Problem

Existing turbocharger testing methods cannot accurately assess the non-equilibrium condensation flow of high-humidity exhaust gas from hydrogen internal combustion engines, resulting in inaccurate efficiency measurements and an inability to assess the risk of water erosion. Existing testing methods also ignore the phase change characteristics of high-humidity exhaust gas.

Method used

The air temperature and humidity are independently regulated by the intake conditioning device. Combined with the optical droplet detection device and the actual gas state model, the non-equilibrium condensation flow is monitored in real time and the data is corrected to assess turbine performance and water erosion risk.

Benefits of technology

It enables high-precision testing of turbine performance and accurate assessment of water erosion risk, eliminates the interference of thermal throttling effect on efficiency calculation, improves the reliability of test data, and can identify performance deviations and water erosion risks at the prototype stage.
