The article discusses the relevant and practically significant problem of improving the efficiency of ventilation and aspiration systems. Special attention is paid to the methods of controlling the air flow using various regulating devices, and in particular, slide gates, which are widely used in the industrial and domestic sectors. The main purpose of the conducted research is to create and critically analyze an adequate CFD model of a slide gate, while using the powerful SolidWorks software package to implement both geometric modeling and subsequent numerical calculations. During the research, a detailed computer model of a slide gate was created, and the dependence of the local resistance coefficient (ζ) on the flow area was studied. The obtained numerical results were compared with data from reference sources. The results of the numerical experiment demonstrated high accuracy of the predictions and the reliability of the constructed model, which is confirmed by small deviations from the reference values. Based on the analysis conducted, it was determined that the developed CFD model of the slide device can serve as a reliable foundation for further research, optimization, and improvement of ventilation and aspiration systems. The use of software products such as SolidWorks significantly simplifies and accelerates the process of designing, modeling, and analyzing ventilation characteristics. The obtained data can have practical significance in various industries where efficient airflow management is crucial for ensuring a comfortable microclimate and energy efficiency.
