Vortex Ventilation: Shaped Units of Energy-Saving Ventilation Systems presents the methodology for conducting numerical and experimental studies of separated flows in various elements of ventilation systems, which can serve as examples for conducting similar studies for undergraduate and graduate students. The dependencies obtained as a result of the research presented in the book can be used by designers when developing projects for ventilation systems with reduced energy consumption and cost. Due to shaping along the outlines of vortex zones, the shape of the ventilation elements change, which leads to a decrease in the aerodynamic resistance of both the elements themselves and the entire ventilation system as a whole. This in turn leads to a reduction in energy consumption and lowers operating costs. Further, with a large number of shaped elements, a general decrease in the resistance of the system leads to a decrease in the size of the fan, etc., and the cost of the ventilation unit, which can also decrease capital costs.
- Includes detailed algorithms for numerical and experimental research and development of improved duct fitting elements of ventilation systems.
- Describes the application of the discrete vortex method to ventilation problems.
