Prediction model of decompression wave velocity in supercritical CO2 pipelines containing impurities
Once a supercritical CO2 pipeline fractures, decompression wave will appear at both end of the crack. Hence, the calculation of the decompression wave velocity during the pipeline fracturing is critical for the prediction and control of pipeline fracture.
