TY - JOUR A1 - Pérez García, José AU - Sanmiguel Rojas, Enrique AU - Viedma Robles, Antonio T1 - New coefficient to characterize compressible flow at T-junctions Y1 - 2010 SN - 0307-904X UR - http://hdl.handle.net/10317/1549 AB - A new coefficient to characterize the global behaviour of adiabatic compressible flow at T-junctions is proposed. The new coefficient is defined according to the conclusions derived from the uncertainty propagation analysis of the total pressure loss coefficient defined by Miller for compressible flow. The numerical results obtained using the new linking between branches coefficient definition, K, show a logarithmic relationship with mass flow rate ratio between branches, q , and the extrapolated Mach number in the common branch, M*3 , for all flow types studied in a 90 degree T-junction. Reliable and practical two parameters or global correlations, K=K(M*3,q), have been btained. These correlations can be easily implemented as boundary conditions into 1-D global simulation codes.
