hi all,
i want to use the phase velocities at boundary surfaces in my udf. for the single phase flow, the variables are F_U(f,t), F_V(f,t), F_W(f,t) but i couldnīt find any information about the variables corresonding to the different phase velocities in multiphase flow. i am using Eulerian Model. thanks for any help concerning. kerem |

i actually found the answer in an example; the phase velocities of such form are used for an Eulerian two phase (gas-solid) model:
vel_gas_x = C_U(cell, thread_g) vel_gas_y = C_V(cell, thread_g) vel_sld_x = C_U(cell, thread_s) vel_sld_y = C_V(cell, thread_s) and likewise -i guess- for the face velocities. i hope this helps you too.. kerem |

oops,
forgot to mention the definition of the sub thread: thread_s = THREAD_SUB_THREAD(thread, phase_identifier_solid) |
