I am trying to do liquid liquid extraction using VOF model in a stratified flow of two immiscible liquids ( 1. mixture of toluene and acetone 2. water) I want to extract acetone from the mixture to water across the interface.
#include "udf.h" DEFINE_MASS_TRANSFER(source, cell, mix_thread, from_index, from_species_index, to_index, to_species_index) { real m_lg; Thread *pri_th, *sec_th; pri_th = THREAD_SUB_THREAD(mix_thread, from_index); sec_th = THREAD_SUB_THREAD(thread, to_index); m_lg = 0.0; if (C_VOF(cell, sec_th) != 1.0) { m_lg =0.00005; } return m_lg; } What macro I have to use to identify the particular species (acetone) in a mixture and transfer it across the interface. Thanks in advance |
