...You can derive all of Navier -Stokes from this fundamental approach. The summation of forces from all of these individual collisions results in a lift vector that is a function of airfoil shape, relative speed, and angle of attack. Whether you capture this on the macro level in the form of pres...

100LL: EPA proposed endangerment finding

...Run navier stokes equation in a computational fluid dynamics estimate for air flow over a wing and refuse to interpret the results since this is only one data point and so I can't compute a correlation. Tell you what- your comfort with making important decisions with incomplete information, i... -
...there are the Navier -Stokes equations used by engineers that accurately describe the behavior of fluids in motion and allow prediction of aerodynamic forces, but do not provide much physical insight. On the other hand, there are the popular explanations invoking Bernoulli and Newton that are easy t...

...(s) Navier and Stokes have visited here before... https://mooneyspace.com/search/?q= Navier &quick=1 We have a few people around MS that are familiar with both the fluid flow and the math... Best regards, -a-

...The dominant equation is "Reynolds Equation" which is a simplified version of Navier Stokes for fluid flow. Over 100 years and the math still works :-) My work is actually with bearings that work with air (we design and make air foil bearings), but I started with gas turbines using conven...

...the equations involve full Navier -Stokes equations, which include Bernoulli and Newton. 2. If you believe a typical Mooney wing has laminar flow further aft than other airplanes, I have ocean-front property for you in Arizona. Sorry. Please note that there are basically 3 types of boundary l...

...we only know the airflow speed/pressure at the start and end of that big wind tunnel Of course you can run Navier -Stokes equations on a super computer and check accuracy versus analytical solution on simple cases or empirical results on reduced models When I used to work on these,...

...They are both utilized in the Navier -Stokes equations that used to be computed by hand, but are now imbedded in CFD programs. For real CFD simulation, the boundary layer also has to be modeled. There are also good CFD programs that model well enough to run loads programs and the like. Some of t...

...let alone the whole aircraft (see navier stokes equation) alone. Fwiw, neither does Bernoulli, to get to his equation, you also have to make simplifying assumption that does not take into account spanwise lift, amongst other things, for instance, but it is also derived from the conservation of mom...
