FIG. 11. — Normalised pressure drop for various Re across the contraction for a geometry with l_c = 2w_u, l_ε = w_u, CR = 8 and (a) AR = 1, (b) AR = 2, (c) AR = 4, and (d) AR = 8, with the horizontal dashed lines indicating the normalised pressure drop value under creeping flow conditions. The inset figures in (a)–(d) represent the normalised pressure profiles along the centreline for each case, with the vertical dashed lines indicating the start and the end of the transition region of the contraction/expansion.
