At inlet-1 at time t1, secs, enters hot gas with velocity v1 and lasts for Dt1 secs. At time t2, secs (t2>t1+Dt1) gas starts to enter inlet-2 with velocity v2 and lasts for Dt2 secs. Conditions at outlet are to be found? I tried but didn't find time domain definition (similar as steps in f.e. transient structural). Would be very grateful for tips?
