  • 15:19, 19 April 2020 Samarsden talk contribs created page File:Recirculating Plugs.png (Adapted from (Bringer, 2004). This shows the movement of both the plugs and the internal fluid. In the top system, along a straight channel there is radially symmetrical mixing with constant vortices, only mixing certain sections of the plug. In the bottom system, along a curved channel there is no longer symmetry. Along a curve, the outside of the plug has more surface area in contact with the wall while the inside has less, resulting in a larger vortex on the outside of the curve and a smal...)

Mixing by (a) steady, recirculating flow and (b) chaotic advection. (i) Mixing represented by schemes of flow in a flow cavity; (ii) images of flow in a flow cavity (reproduced with permission of Cambridge University Press from Ottino (1989)); and (iii) schemes of flow in plugs moving through (a) a straight and (b) a winding channel (Bringer, 2004))

  • 14:46, 19 April 2020 Samarsden talk contribs created page File:No Slip BC.png (No-slip (a) and slip (b) boundary conditions. In no-slip boundary conditions, the speed of the fluid at the wall is supposed to be zero, whereas in slip boundary conditions there is relative movement between the wall and the fluid. Most fluid mechanical problems on liquids can be considered using no-slip boundary conditions if the characteristic length scale Lchar is bigger than 300 nm (Rapp, 2017))
