 July 3, 2003, 13:44 Particle tracing and Re #1 Jackie Guest   Posts: n/a Hello all, I have two questions waiting for suggestions please. 1. I like to put a particle at the inlet boundary and see it's tracing line, but I don't know how can I create a particle and put it in that location. 2. I simulated the flow in a stirred tank. After running the program, relevant Reynold's numbers were reported. Could anybody explain how CFX compute the Reynold's number. Thank you in advance for all kind answers. Jackie.

 July 4, 2003, 06:24 Re: Particle tracing and Re #3 Jackie Guest   Posts: n/a Hello zdong, Did you mean I just simulate stirred tank as one phase flow and put a particle in the tank later? Can I simulate them as a multiphase flow?, and how can i input a parameter of a particle? such as density, size, number of particle, volume fraction ,or initial location et al., Jackie

 July 9, 2003, 15:35 Re: Particle tracing and Re #8 chris Guest   Posts: n/a Hello, Streamlines correspond to particles of zero mass. If you want to simulate particles with non-zero mass use the Lagrangian Particle Tracking as described in the new "Butterfly Valve" Tutorial of CFX5.6. Chris

 August 11, 2003, 23:12 Re: Particle tracing and Re #9 Paul Guest   Posts: n/a My understanding is that you were not able to put the particle in the command file and track it in the flow. in order to do that, you can refer to one of examples of particle tracking of CFX4-4 (i am not sure what examples are available in CFX5). If you have further questions, I will give some details. good luck
