UDF for heat addition and mass addition -- CFD Online Discussion Forums

September 20, 2006, 08:57	UDF for heat addition and mass addition	#1
Srikanth Guest Posts: n/a	I am trying a validate an analytical work with CFD calculations. Analytical work was carried out for a hyperbolic nozzle where in heat addition and mass addition are considered. Total temperature at inlet=1000 R. Linear variation of total temperature along the length is assumed and is given by the relation 1000+(20*x). Also in the same problem there is mass addition.Mass flow rate at inlet being 100 lb/s, at the exit it is 110 lb/s also varying linearly as 100+x. Should I write an UDF to do this or are there any other option? Incase UDF is the only option...Can anybody help?
