Abstract
Research relevance. The paper establishes the regularities in the impact the geometry and structural elements of a fan system piping have on the fan system’s aerodynamic efficiency in a wide range of the specific speed variation. Objectives and methods of research. A mathematical model has been obtained for the dependence of fan system’s geometry and kinematic parameters and the aerodynamic efficiency on the specific speed. Results. It has been proved that in order to reach higher aerodynamic efficiency of fan systems, in view of the increasing specific speed of fan systems, the aerodynamic quality of the impeller blade profiles should be increased and the aerodynamic resistance of the piping elements should be reduced. It has been shown that it is possible to create a gas cooler fan system with at least 400 specific speed and at least 0.85 efficiency if the impeller profiles aerodynamic quality is more than 25, and piping drag coefficient doesn’t exceed 0.2.
