How Do I Calculate Lift and Drag with Winglets?

[sakthivelzz]

Hi I need to know how to calculate lift characteristics like cl ,cd and so on... how can we include the winglets in it?

 

[viscousflow]

Wind tunnel... cfd... addition of winglets is a non-linear problem.

Can u explain it in more clear way please??

why don't you just look through Fundamental of Aerodynamics and Low speed aerodynamics books to get some sense about how to calculate lift and drag ?
Then you come up here again and ask what you need exactly. You need to specify
your flow condition like airspeed..based on that we must imposed some laws: for instance,
compressible or incompressible,potential flow is applicable or not?
Those kinda things have to consider before you get your solutions. For CFD, you must define your geometry first..then..grid..then solver like potential flow solver or Full Navier Stoke equations. I recommend you read the books I mentioned and try to get some senses firstly.
