Simulation analysis method and device for automobile fan and storage medium

The invention discloses a simulation analysis method and device for an automobile fan and a storage medium. The simulation analysis method comprises the following steps that S1, a basic whole automobile analysis model is established; s2, establishing a fan independent analysis model; s3, establishing a fan default whole vehicle analysis model; s4, analyzing and solving the basic whole vehicle analysis model to obtain initial flow field information; s5, analyzing and solving the fan independent analysis model to obtain a second initial boundary of the fan default whole vehicle analysis model; s6, analyzing and solving the whole vehicle analysis model with the fan default to obtain flow field information; and S7, through the fan independent analysis model and the fan default whole vehicle analysis model, multiple coupling solution calculation is carried out until convergence, and a converged whole vehicle flow field and temperature field analysis result is obtained. The method can improve the calculation precis
