SUMMARY

This discussion focuses on simulating the flow around a 2D airfoil at Mach 0.9, highlighting the need to account for compressibility effects and transonic flow. Recommended literature includes "Theory of Wing Sections" by Abbott and Doenhoff, which provides foundational knowledge on airfoil theory. The conversation emphasizes the importance of advanced methodologies, such as finite difference methods and the Navier-Stokes equations, for accurate simulations. Participants express a desire to revisit these simulations to explore unsteady aerodynamics.

PREREQUISITES
  • Understanding of compressibility effects in fluid dynamics
  • Familiarity with transonic flow principles
  • Knowledge of finite difference methods for flow simulation
  • Proficiency in Navier-Stokes equations
NEXT STEPS
  • Research advanced simulation techniques for compressible flow
  • Study the application of Navier-Stokes equations in aerodynamic simulations
  • Explore unsteady aerodynamics concepts and methodologies
  • Review additional literature on NACA airfoil design and characteristics
USEFUL FOR

Aerospace engineers, fluid dynamics researchers, and students interested in advanced aerodynamic simulations and the effects of compressibility on airfoil performance.

I would like to simulate the flow around a 2D airfoil up to M=0.9.
Could you please recommend me some bibliography?

Is it a well known type of airfoil (typical NACA designation)? If so, there are quite a few books that would probably have all of that information available already.

The problem is, you want to go all the way up to Mach 0.9, which means you will start getting compressibility effects and all of the effects of transonic flow. You would likely need to go well beyond the basic theory of airfoils to get an accurate answer. In other words, how accurate does your answer really need to be?

At any rate, "Theory of Wing Sections" by Abbott and Doenhoff would likely be a good starting place.

It would be a NACA, but I am not sure the designation. In fact, I'm more interested in the methodology to perform the simulation.

When I was taking aerodynamic classes, I remember I did a flow simulation around an airfoil using finite differences. I don't remember if I used Navier-Stokes or Euler. Since it was about 15 years ago, I can't remember the details.

I would like to be able to do such simulations again, this time to study the unsteady aerodynamics.
