    Difference between velocity potential and circulation

    I think you need to elaborate... Circulation is merely a defined as a velocity integral along a closed path, velocity potential is based on Helmholtz-Decomposition which decomposes the flow field as a scalar and vector potential. The vector potential is basically vorticity. When you ignore the...

    Blade Element Momentum Theory

    Since the turbine generate a pressure field upstream the blades of that turbine do not see the undisturbed flow field, they see a flow field that has already been modified by the turbine. So this created a circular problem: to estimate the modified flow field I would use 1D momentum theory and...

    Drag Forces in simple sweep theory...

    Thanks SparWeb for helping with this... I actually do not care too much about the lateral forces nor span-wise flow... I know realistically they are small enough to ignore at the design stage where simple sweep theory is relevant... This is probably more of a geometry convention questions. So...

    What programming languages should an aerospace engineer know?

    Hello There I think the question of what language is 1) a matter of what you want to use the language for and 2) who you would be sharing your code with. I think it is too simplistic to say one is the best, they all have their niches. Forgive me but since I have a extensive experience...

    Drag Forces in simple sweep theory...

    Hello Folks I want to calculate the sectional drag force vectors for a swept wing. According to simple sweep theory for lift one ignores the span-wise component of the flow, then in the reference frame perpendicular to the wing one calculates the AOA, look up Cl and voila you have your...
