XFLR5 PART1 AIRFOIL ANALYSIS | HANDS ON TUTORIAL SERIES

[@adamhale6672]

I was recommended some different tutorials to learn this software, but this was much clearer and concise that the others I was trying to watch. It also uses the updated version of XFLR5. Thank you!

You are welcome Adam, thanks for the feedback and nice comment ☺

Thanks, Great Work, where was this when I was studying, looking forward to designing some test wings and 3d printing for RC slope soaring.

[@apoorvsom9120]

Wow! Thank you very much for such a nice explanation. I have watched several videos but they take so much of our time explaining things not much relevant to me. This was a perfect video. Good job!!

Fantastic Tutorial - really clear and at a good pace

[@Simulation-Engineer]

Thanks a lot for the feedback.

😂

[@61Ertu]

You even did the validation, thanks man.

[@Simulation-Engineer]

You are welcome thanks 👍

[@TheAeroAceMix]

Re Validation, Xfoil is very well validated so there is no suprise there. Im looking forward to seeing how acurate the 3d stuff is. PS thanks for this

I have a problem related to simulating FX 61128 airfoil using XFLR5. I don't get any results on analysis. The question is can I get results for any random airfoil? Or Is it like a predefined set of airfoils which are used for wing analysis?

hi I am just curious in minute 12.14 where u stated that "viscous effect is not actually calculate here". However there is a viscous function and a display of displacement thickness which through my imagination that is actually a boundary layer.

[@Simulation-Engineer]

- With this I mean there are some limitations within xflr5 to calculate viscous effects. That is there is lack of interaction between boundary layer and inviscid flow. Also the estimation of viscous drag. - Potential methods such as VLM and 3d Panel methods merely interpolate 2d viscous drag from local wing lift that is not good. - Their is lack of interactive boundary layer loop, which is a coupling method between potential flow and viscous flow on surfaces. - The effect of the boundary layer is to modify the geometry of surfaces and to disturb the inviscid potential flow. - A loop is therefore needed to reach a solution that satisfies both the viscous model and the potential flow model. - This loop is not implemented in the panel methods available in xflr5. - Consequences / drawbacks are: * The lift is a linear function of the a.o.a., unlike with XFoil or with the non-linear LLT. * Significant differences in the lift coefficient predictions at low Reynolds numbers. * The potential flow model is only valid in conditions of limited flow separation. Hope this helps, thanks.

Quick tip, if your graphs look like a 3 year old scribble, right click and reset the scale ;-p

[@sarandicarlomichael2109]

Hello, I have the updated xflr5 but the graph isn't coming out

[@Simulation-Engineer]

Can you explain which graph is not coming out?

[@astikshrivastava6946]

I cannot see any graph on operating view. Also the polars I'm getting are not what are shown

[@Simulation-Engineer]

Plz check the xflr5 setup in case you missed something and normally you should get similar results, thanks

[@E101STUNT]

My friend said you deserve sloppy toppy for this

[@kesmirsavasci3123]

How can i install xlr5.

[@Simulation-Engineer]

Here is the installer: sourceforge.net/projects/xflr5/files/6.57/
