Vortex Lattice Method: Find Airfoil Equation for Designing

AI Thread Summary
The discussion centers on using the Vortex Lattice Method (VLM) for airfoil design, specifically seeking the equation for an airfoil. A link to the NACA airfoil equations is provided for reference. However, it is clarified that VLM cannot be used to design an airfoil directly, as it models lifting surfaces with horseshoe vortices and does not account for airfoil thickness. While there are methods to simulate camber effects, the limitations of VLM in airfoil design are emphasized. Understanding these constraints is crucial for effective application of the Vortex Lattice Method in aerodynamics.

The equation for NACA airfoils is in the link, together with a description. What more information do you need to get started? Where do you get stuck?

Hello!
I have some queries regarding Vortex Lattice Method.
I want to design an airfoil using Vortex Lattice Method. For that, I need to find out the equation of airfoil first.
So how exactly am I going to do that?
Please refer the following link: http://en.wikipedia.org/wiki/NACA_airfoil#Equation_for_a_symmetrical_4-digit_NACA_airfoil

Thank you!
You cannot use vortex lattice to design an airfoil. Vortex lattice models lifting surfaces as a series of horseshoe vortices on surfaces of zero thickness. There are ways that you to some extent simulate the effects of airfoils camber using vortex lattice method but in general the vortex lattice method does not take into account the airfoil.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
