Difference between experiment & Simulation data
1 Attachment(s)
I had made a triple laminar flow in below 1mm diameter, length 10cm capillary tube.
Water goes through Each 3 inlet right side and left side is a outlet First, I did the experiment using a 2 color dye and found that the triple laminar flow was remained till the end of capillary(10cm) But after I did the simulation using ansys fluent, 3 water components totally mixed less than a 3 cm So I want to find the error in my simulation process. add 3 waters in materials - fluid Multiphase model - explicit check, implicit body force check - dispersed check Multiphase model - phase 1, 2, 3 to water 1, 2, 3 viscous model - laminar(very low flow rate) or just used k-e model Boundary conditions - inlet 1 (middle) -> 0.52ml/min to linear velocity, inlet 2 -> 0.04ml/min, 3 -> 0.04ml/min, Volume fraction inlet 1 -> water1 : 1. same as inlet 2, inlet 3, K, e : 1 Methods : Piso or simple Monitors - Residual : all components to 1e-7 Initialization : Inlet 1 Run calculation : Time step size 0.005 s, Number of time steps : 10000, Max iterations/Time step : 20 Every condition showed same simulation results.. Anyone please tell me the problem..? Thank U! |
