  • 20 dipoles swimming around 20 inviscid doublets advecting themselves around in 2D. The rotation of the doublet axis was obtained by integrating the torque exerted on the doublet solid body (phi=0) only over the side facing the influencing doublet - ie the doublet doesn't "see" the backside of other doublets. This is a fudge since the potential flow field is irrotational - and so integrating over the closed contour would produce zero torque. A simple Euler integration scheme was used, and 10000 passive tracer particles coloured by velocity magnitude were added for effect. dx(i) / dt = SUM j=1..N, j/=i [k(j) * ((y(j) - y(i)) * cos(q(i)) - (x(j) - x(i)) * sin(q(i))) / ((x(j) - x(i))^2 + (y(j) - y(i))^2)] dy(i) / dt = SUM j=1..N, j/=i [k(j) * (-(y(j) - y(i)) * sin(q(i)) - (x(j) - x(i)) * cos(q(i))) / ((x(j) - x(i))^2 + (y(j) - y(i))^2)]

  • Stream-function (around an oscillating cylinder) - CUDA This simulation was created using an in-house code. The original version of the code was run on the CPU, but now it' runs on GPU, and finishes simulations around 6-8 times faster on GTX295 (using the first card) than a CPU. The cylinder is oscillated in a low Reynolds-number flow on a circle. Program developed by: Prof. Laszlo Baranyi (University of Miskolc, Hungary) - mathematical and physical model Laszlo Daroczy (University of Miskolc, Hungary) - programming (algorithms, graphics, CUDA)
