“…POCS fluid dynamic behavior is investigated in the fully developed regime, neglecting any influences due to entrance effects and lateral constraints. To describe and analyze the fully developed regime in POCS, periodic boundary conditions are implemented for all the relevant variables. ,, Under fully developed flow conditions, the physical properties of interest (i.e., fluid specific flow rate, pressure, composition, and temperature) are reduced to periodic functions in the streamwise and transverse directions. Details on the implementation of periodic boundary conditions for compressible flows in the three-dimensional space are reported in the Supporting Information, Section 1.3.…”
