    Order of induced velocities due to vorticity

    ...least a million particles. But my question here concerns only two particles. What will be the order of induced velocity if the vorticity of particles is given a value, say, (1/4*pi)*(exp(-r2/sig2)), where 'sig' represents the particle radius and r is the distance between particles in 3D...

    Book to learn Vortex Methods from.

    MOHR1951, yes, your suggestions helped me in learning about the method in question. But I was also able to find a book titled Vortex Methods and Vortex Motion by Karl E. Gustafson and James A. Sethian. The first two chapters in this book are gems. They really helped me understand the fundamental...

    Book to learn Vortex Methods from.

    Hello everyone, Does anyone know of a good book to learn vortex methods from? I have tried learning about the methods from the book Vortex Methods-Theory and Practice written by Petros Koumoutsakos & Georges-Henri Cottet, but I'm unable to understand the fundamentals when reading that book. I'm...

    Wind Turbine wake modeling

    Hello everyone, I want to numerically model the wake (near and far wake) of a wind turbine. Where do I begin my research on this topic? How much knowledge should I have to perform this? Thanks for your answers! vktsn0303

    JavaFoil

    Hello everyone, I want to construct a NACA 23012 airfoil with a slotted flap using JavaFoil. I've been trying to learn how to do this by searching on google but it just doesn't seem to be helping. The JavaFoil's userguide pops up but it doesn't seem to be of much use to me. It would be helpful...

    Sketching streamlines

    Hello everyone, I was reading about the strain rate tensor and other kinematic properties that can be obtained with the help of the velocity field and I was wondering if we could determine the streamlines if we had the strain rate tensor to start with. Let's say I have a strain rate tensor...

    Using a turbulence model in a numerical wake modeling technique

    If I were to model the wake of a wind turbine using a certain numerical method should I, or should I not, take into consideration a turbulence model and couple it with the numerical method being implemented? It would be helpful to know the reasoning behind your explanations too. Thanks in...

    Routing Electrical - routing many routes between two points

    Hello everyone, I wanted to know if it was possible to route many possible routes between two given points with the input being just the two given points. Let us suppose point A(x1,y1,z1) is fixed and point B(x2, y2, z2) can be moved(either along a circle or translated along a vector but not...

    Current issues faced by the aerospace industry

    Hi everyone! I wanted to learn about the issues that the aerospace industry is currently facing. I searched on the internet about this but could not find a proper web site that explains the issues well. So I thought this forum was the right place to ask about this. I would be glad if anyone...

    Python IDLE does not start

    It works!! I added the executable file location to the path under system variables and it opens when I say 'start idle'. Thanks vktsn0303

    Python IDLE does not start

    Yes, going to the file location and running the executable starts it. I just wanted to open it through cmd. I feel it's easier to do that than going all the way into the file location and scrolling through the files and selecting one of many present there. When you say path I am assuming you are...

    Python IDLE does not start

    Hello everyone, I'm new to Python programming (and a novice in programming). I can't get to start IDLE when I type 'start idle' in my command prompt. An error pops up saying 'windows cannot find idle. Make sure you typed the name correctly and try again.' I use Win 7. Please help. Thanks...

    What programming languages should an aerospace engineer know?

    From the discussion so far I take it that Python is equally powerful and helpful as matlab is but the latter being able to offer easier access to versatile tools readily. vktsn0303

    What programming languages should an aerospace engineer know?

    I'm sorry GregLocock, I am uable to recollect the Where, When and Who. It was nearly a month ago that I had come across the article somewhere on the internet. But I have been having this doubt for a long time. vktsn0303

    What programming languages should an aerospace engineer know?

    I thought aerospace engineers used only MATLAB extensively. But on the internet I have come across articles that suggest learning JAVA and VBA to be helpful. Is it true that even aerospace engineers use languages like JAVA, C++ and VBA extensively? vktsn0303
