Urea spray model calibration method based on correction technology and test

The invention discloses a urea spray model calibration method based on a correction technology and a test, and the method comprises the steps: determining a parameter input data sample through employing an optimal Latin hypercube test design method according to the adjustable range of model parameters; performing calculation in CFD software to obtain output result data corresponding to the input, and performing fitting processing on input/output sample data so as to construct an agent model; solving and calculating the agent model by adopting a particle swarm algorithm to obtain a spray model parameter calibration value; a matched test bed is designed according to the spray model, a high-speed camera is used for recording the spray atomization process, a result and a calibrated spray model numerical simulation result are compared and analyzed, whether an error allowable value is met or not is judged, then the urea spray model parameter calibration efficiency is improved, the spray model calibration accuracy i
