Optimization adjustment method of duct valves based on Kriging approximation model

Presents the approximation model theory and multi-objective particle swarm optimization algorithm. Establishes a numerical model for the air supply mode of the air conditioning system in an aircraft spray-paint workshop by Fluent software.Generates the valve opening configuration using Latin hypercube sampling method.Obtains the sample data by multiple simulation runs. Establishes an approximation model of the relationship between the reciprocal of valve opening in air duct and the standard deviation of air volume by Kriging algorithm.Obtains a Pareto frontier by the improved multi-objective particle swarm optimization algorithm.
