good cold flow results but problem with hot flow
Hello Friends,.. I have posted this many times but could note get any help,.... I have very short time to complete my project,... Please help me,.... if u know anyone who can help me please give me the contact i.d's,....... Pleaseeeee
i have got good results in agreement with the experimental values for cold flow analyis,... but when am starting combustion on the same geometry,... am getting negative pressures at the throat of the inlet and oulet nozzles of the combustion chamber,... this negetive pressures is not dying down but going on increasing,...
am doing non-premixed combustion using mixture fraction/pdf model,...
am unable to locate where the problem lies,.. is it in the pre-pdf or any where else,...
My inlet boundry conditions for hotflow are
Pressure inlet : 60bar at inlet nozzle
Pressure oulet : 0bar (i.e atmospheric pressure ) at outlet nozzle
Wall Temperature : 500K
Operating pressure is 0 pa
Please help me in solving my problem,..
