Hi!
I would like to simulate particle flow around a 2D cylinder and get the impaction efficiency eta of the particles on the cylinder's surface, which is defined as: eta = dN/dt / F, where dN/dt is the no. of particles captured on the surface in the time interval dt and F is the particle flux. I use the 'stick-to-wall' BC for the cylinder surface. Now, I have the following questions: 1. How can I get dN/dt, eta? 2. 1. How can I plot dN/dt, eta during solving? 3. Are the particles, once they get captured by the "stick-to-wall" BC, removed from the domain, or are they still being tracked afterwards? 4. If the are still being track after capture, how can I make them disappear, once they impact on the cylinder's surface? Cheers, Julian
