Mathematical Description of the Aerodynamic Characteristics of Stationary Flows in a Vertical Conical Diffuser When Air Is Supplied through Various Tube Configurations

Conical diffusers of various configurations are used in many kinds technical equipment and manufacturing processes. Therefore, it is a relevant objective to obtain reliable experimental mathematical data on the aerodynamic characteristics diffusers. This article presents aerodynamics stationary flows vertical conical diffuser when air supplied through tubes with cross sections (circle, square, triangle). Instantaneous values flow velocity measured constant-temperature hot-wire anemometer. Data obtained fields turbulence intensity along height diameter diffuser’s cylindrical part configurations. It established that supply profiled has significant effect shape field diffuser. For example, higher typical (the differences reach 50%). A formulation (linear exponential equations) change average speed for initial conditions tube presented. The findings will make possible refine models update algorithms engineering design processes pieces equipment.
