چکیده
Since its inception in the early 1970s by Daniel Gurney, Gurney flaps have proven to be an effective means of enhancing aerodynamic performance airfoil. Current applications include wind turbine blades, race car spoilers, helicopter rotors, and certain high-lift devices. This study compares influence on flow characteristics effects design parameters flap, namely length position flap a NACA 23,112 A review studies conducted so far has shown that been carried out select few airfoils only mainly studied variation one characteristics, like length, position, or angle. paper crried find optimum balance between these parameters. Additionally, this aims investigate accuracy feasibility numerical investigation methods estimate wings compared conventional techniques tunnel testing. cost-effective computation method is less susceptible external factors weather changes. The CFD process also allows testing at conditions might otherwise impractical test tunnels. workflow comprised literature, validation solver settings, preparation model, extraction results analysis results. Autodesk Fusion360 Ansys Workbench 22R1 were used make models. airfoil designs tested Re = 2 × 106, angles attack varying from 0° 15°. GF height ranged 1% 3% chord placed 95% 100% chord. reliable methodology arrived validated implementing best practices prescribed for CFD. k-ω SST turbulence along with second-order spatial discretization, was used. Coefficients lift drag considered found increase airfoil, better obtained higher attack. modified noted separation point further downstream than baseline model. Overall, presence proved beneficial over

experimental and numerical investigation of aerodynamic characteristics of a circular cylinder in an axial flow
in this study, aerodynamic characteristics of a circular cylinder in an axial flow have been investigated numerically and experimentally. the model has been considered as a cylinder with truncated nose and fineness ratio of 3 (length to diameter ratio of 3). the investigation involves a series of wind tunnel measurements, flow visualization, and numerical simulation. we used different mach numb...
متن کاملNumerical Investigation of Fluid Flow Characteristics Around Slide Gates Using Multi-Zonal Method
One method of solving the governing equations of fluid flow about complex geometries is to use multi-zonal method. In this method the overall domain is divided into small number of simpler domains. In each zone, the flow field is solved independently of other zones. The boundary conditions for connecting zones are enforced to convey the necessary linkage. This multi – zonal procedure has been a...
