A. Attou et Jm. Seynhaeve, COMPUTATION OF STEADY-STATE MULTIPLE CHOKED COMPRESSIBLE FLOW - AN ANALYTICAL SOLUTION FOR SINGLE-PHASE AND 2-PHASE 2-COMPONENT FLOW, Journal of loss prevention in the process industries, 11(4), 1998, pp. 229-247
The possibility of multiple choked compressible flow is analysed for t
he single-phase gas and two-phase two-component mixture. Two basic cri
teria derived from the global mass and energy balance equations and fr
om the second law of thermodynamics have been established for describi
ng the occurrence of multiple choked flow phenomenon. An analytical co
mputational procedure deduced from these criteria is proposed and appl
ied to the practical case of flows through a discharge line involving
several singularities. Comparisons between simulations and experiments
performed with pure nitrogen and nitrogen-water mixture show a good a
greement. (C) 1998 Elsevier Science Ltd. All rights reserved.
