| Title of the article | Flow to a lateral exhaust device located above an impermeable plane |
| Abstract. | One of the methods for improving the efficiency of local ventilation is to improve the design of its elements - ventilation exhaust, in order to reduce aerodynamic drag. To do this, the outlines of the vortex zones should be determined. For the case of the exhaust location next to an impermeable plane, the outlines of the vortex zones and the velocity field will depend on the distance to the impermeable plane. Determining this dependence for the case of lateral exhaust is the goal of the study. To achieve the goal, the following tasks are solved in the work: verification and validation of the numerical solution of the problem using different combinations of the turbulence model and wall functions are carried out; flow characteristics at the inlet to the air duct are determined at different distances from the solid wall; dependencies of the outlines of the vortex zones and the local resistance coefficient and the velocity field on the distance to the solid flat wall are revealed. Results. The combination of "turbulence model + wall functions" was selected, which most adequately reflects the main characteristics of the flow at the inlet of the exhaust air duct, located at different distances from the solid wall. The values of the local resistance coefficients and the outlines of the vortex zones for the studied distances were determined. Conclusions. The distribution of air velocities at the side exhaust over the impermeable plane obtained as a result of the study can be used in engineering calculations of local exhaust ventilation |
