NACA Airfoil SolidWorks Flow Analysis's tutorial | Aerodynamics | Drag Vs Lift Force

Aim : Model the flow over a NACA0017 Airfoil for the angle of attack 0,2,4,6,8,10 Compare the lift anddrag force.
Introduction : The NACA Airfoil are Airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties.
In my case according to create project in NACA0017 Airfoil which data file is download from official website of airfoiltools.com
Procedure :
1.) first to import data file in solidwork and convert in to entity.
2.) adjust angle for requirement from 0 to 10 degree and the convert in to solid part.
3.) create wizard for external simulation and use time dependent.
4.) use air as fluid flow 600 m/s in x direction.
5.) remain use default .
6.) convert computational domain in 2D and adjust according to flow.
7.) use global goal (Normal force in (X) and (Y)) direction and friction force in (x) and (y) direction.
8.) also use surface goal for friction forces in (x) and (y) direction.
9.) use basic and local mesh in the surface.
10.) and the RUN the program.
11.) after completion calculation over result is obtained in result column.
12.) add cut plot for velocity and arrange colour bar for 200 shades of colour.
13.) now we have obtained simulation result for lift and drag force with different colour range.

what's the purpose of setting friction force for BOTH "global goal" and "surface goal"

Thanks for sharing

[@rahulkumarlakshkar1773]

Thanks 👍

Hello thank you for the video. When I run the simulation the Solver gives me a warning "Supersonic flow is detected within a considerable number of cells" and takes a while to run. Any suggestions?

[@Akashi_216]

same did you find any solution ????

[@notdjello]

​@@Akashi_216 if I remember correctly I believe it was the velocity parameter he put was way too high resulting in Supersonic Flow

You need to enable the "High Mach Number Flow" checkbox. This NACA airfoil as shown in the video, is never used for supesonic speeds.
The velocity of air should be around 100-150 m/s which makes 0.3-0.5 Mach flow and 200 iterations per travel.
For high Mach number flow you may create diamond shaped airfoil.

@@coolfreaks68why is this shape not suitable for high Mach

[@vlatkopopovski2685]

The authors have two wrong scientific approaches: researching the creation of Lift force and Low pressure at upper side of the wing, relative to the ground surface and Earth. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force. Low pressure creates force normal to the cord (contact surface), and it name is "aerodynamic force" because is made from the air (aero) in motion (dynamic), or wind relative to the wing (object).

Wow. You are Zenious.

[@vlatkopopovski2685]

Tell me how to find your email, but here, and I will send you The story-line of my book in English.

[@gammarey7070]

somehow it says entity can't be rotated with my NACA2414

[@coolfreaks68]

You need to convert entity. Convert entity can project your spline on any of the front, top or right planes. The projection of the spline will obviously look different on each plane.
You just have to edit sketch on front plane, and then select the spline, then click "Convert Entities".
If you are drawing airfoil, the above process will work.
But if you are drwaing tubercles, then you need to set the entire Y column to zero, and put the y-coordinates in place of the Z column, while importing the spline. Then you "Convert Enties" the spline on the top plane.
