摘要

•Support vector machine is employed to identify the flow patterns in packed beds.•Features of different flow patterns are extracted based on different pressure signals.•Feature extraction is conducted by the PDF, PSD and WES methods respectively.•Three SVM models are trained and their identification ability is compared.•Identification rate of typical flow patterns is up to 96.08%.
