That seems like a slightly different case as the speeding up of the air in that case is done by your lips and so is not reacting against the front of the aerofoil. I could be wrong but I think this is a different problem?
I essentially want to understand weather or not an aerofoil with a zero attack angle will generate lift, i.e. using only Bernoulli.
I have attached an image to illustrate my question, will the orange block lift if airflow is passed horizontally over the top of it?
Many thanks
