TALK=T;RUN( 1, 1) ************************************************************ Q1 created by VDI menu, Version 2019, Date 25/01/19 CPVNAM=VDI; SPPNAM=Core ************************************************************ Echo DISPLAY / USE settings DISPLAY DELTA-WINGLETS BEHIND A CYLINDER PARSOL is used here aimed at the demonstration of the method for the simulation of turbulent 3D flow over a cylinder with attached Delta-Wing Pair. The demonstration case considered consists of a half of cylinder placed in an air flow within a rectangular duct. The delta- winglet is mounted on the wall behind a cylinder. The position of the wingle tip is a half of cylinder diameter relative to the center of cylinder.The right triangle winglet with a hight equal to the duct width has an angle of attack of 45 degree. The pressure difference between the pressure and the suction sides of the winglet is anticipated to generate longitudinal vortex which supresses the flow separation on cylinder and develops well pronounced secondary flow. The task is to calculate the flow and pressure fields along with all related field distributions.
