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.

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..

oops,

forgot to mention the definition of the sub thread:

thread_s = THREAD_SUB_THREAD(thread, phase_identifier_solid)
