Wall surface heating/cooling underwater curved surface boundary layer transition forecasting method

The invention relates to a transition forecasting method of an underwater curved surface boundary layer for wall surface heating/cooling, which comprises the following steps of: acquiring an underwater curved surface appearance, and determining an underwater navigation working condition to be calculated; calculating a laminar flow basic flow field of the underwater curved surface boundary layer under the determined working condition; analyzing the linear flow stability of the elementary flow; in stability analysis, underwater wall surface heating/cooling is considered, a disturbance energy equation is established, and temperature disturbance, viscosity disturbance and heat conduction coefficient disturbance are introduced; the flow direction curvature and the circumferential curvature of the underwater curved surface appearance are considered at the same time; through linear stability analysis, growth rate distribution of small disturbances with different frequencies along the curved surface appearance is obt
