Abstract:
Objective To explore the data on the optimum ventilation cross section for the ultra-clean bench with finite element simulation software to meet the requirements of experimental personnel in normal conditions.Methods Firstly,a finite element model for the vertical flow ultra-clean bench was constructed with SolidWorks software,then fluid dynamics simulation for the model was carried out with Flow Simulation software to analyze the gas flow rate,ventilation volume and ventilation interference of the cross section in case of different openings of the adjustable baffle(the distance of the lower edge of the baffle from the clean desktop),finally the suitable baffle openning was determined through comprehensive analysis.Results Simulation results showed that the gas flow rate and ventilation interfence decreased with the increase of th baffle openning,and the ventilation volume peaked when the baffle openning was 225 mm and had the average value being 376.002 m3/h.Conclusion The ventilation interference,gas flow rate and ventilation volume prove to have optimum results in case the baffle openning is 225 mm and the ventilation cross-sectional area is 0.248 m2.[Chinese Medical Equipment Journal,2024,45(2):28-34]
