摘要

Background

Issues of hydrogen explosion safety are extremely relevant. Search for solutions requires both experimental and computational methods.

Aim

To experimentally study the turbulent combustion of hydrogen-air mixtures and to test the CABARET-COMBUSTION CFD calculation code using the obtained data.

Materials and methods

The study includes experiments conducted in a facility representing a large diameter pipe, as well as numerical simulation of deflagration combustion.

Results

The calculated data on the flame front propagation velocity and pressure dynamics at the shock wave front are consistent with experimental results.

Conclusion

The obtained results indicate the potential of using the CABARET-COMBUSTION CFD code in the numerical solution of hydrogen-air mixture combustion problems. This code and its testing on data obtained with high-quality diagnostics will increase the predictive capabilities of supercomputer simulation for the analysis of hypothetical accidents at a qualitatively new level.
