Summary:The invention discloses a mixed layer thickness identification method based on a random coordinate system. The identification method comprises the following steps: importing flow field data; performing homogenization processing on the flow field data, and marking a fluid domain and a non-fluid domain; identifying an active flow and a passive flow, respectively tracking the characteristic flow lines of the active flow and the passive flow, and determining the boundary of the mixing region; establishing a random coordinate system, and determining an integral path set of the mixed region; integrating all the integration paths to obtain the mixed layer thickness of each integration path, namely obtaining the on-way mixed layer thickness of the mixed region; integral path discrete points with abnormal increase or decrease of the thickness of the mixed layer are screened out and removed; and drawing a curve graph of the thickness of the mixed layer along the flow direction to complete identification of the thicknes
