Type 61 --- TURBID ================== The purpose of the routine TURBID is to identify five parameters of the gas turbine on the basis of the nominal (design) conditions and performances. The following data is assumed to be directly available or easy to be estimated. -Nominal Conditions : (Ta)n ; (pa)n ; (T3)n = T3max ; (N1)n ; (N2)n -Nominal performances : (Wsh)n ; (Picomp)n ; (M1)n ; (e)n = e (assumed to remain constant whatever the regieme may be) The five parameters to be identified are : (M1*T1)/(p1*N1) ; (M3 * T3^(1/3))/ p3 ; D ; alpha and A For more information see the HVAC1KIT manual, prepared by; Jean Pascal BOURDOUXHE and Marc GRODENT Research Assistants Jean LEBRUN Principle Investigator.
