Abstract: Objective To develop a portable aerosol sprayer .Methods With computer aided design(CAD)technology,a three-dimensional model of the aerosol sprayer was built , and the simulation analysis of nozzles was conducted using the computational fluid dynamics ( CFD) technology .Results A model of portable aerosol sprayers was designed .According to simulation analysis , the speed and pressure of aerosol in different locations were obtained and were proved to change with time, providing a theoretical basis for determination of working parameters and structural design parameters of the aerosol sprayer nozzle so that design efficiency and quality could be improved; time and cost could be reduced .Conclusion Through CAD technology,an effective method for rational design and structure optimization of the aerosol sprayer is esta -bished.Hydromechanic problems that used to be solved with physical analogue experiments can be resolved by means of CFD simulation analysis .
