peaker007 is on a distinguished road
To define lift force in gas-liquid flow, the following equation are used.But i am not sure what part of the equation should be used as lift coefficient in interaction panel for phases if udf is used for lift force definition. Who can help me how to define the lift coefficient by UDF using DEFINE_EXCHANGER_PROPERTY? Thanks.
