<p>In the last two images the injection start at the throat of the nozzle, this is something of the setup, nothing actually related or that influence this behaviour, because i also tried injecting the particle from the entrance and they have the same differences. I read both equations, but simply this doesnt make any sense. for the same configuration of fluid dinamic study and the particles, with just the difference of the turbulence model. <br>In order to obtain the result i expected, i needed a Time Scale Constant for turbulent dispertion of 10 inseat of the 0.15 but i search about this and it would be ok to use 0.15 for k-omega model, and it doesnt make sense such difference between two models, because i used 0.15 of time scale for k-epsilon. The only information i got about this, is this: <\/p><p>it suggest to change epsilon for 0.09k\/omega, in the equation 0.024 but it doesn’t explain too much about the C_L. It says its not well know bot they got an aproximation that is not explained too. <br><br><br><\/p><\/p>\n","protected":false},"template":"","class_list":["post-382215","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
