“…For regions of parameter space in which the use of zeroth order continuation is unable to converge to a solution, first order continuation (23) is used. To validate the base flow code, comparison was made to previous numerical results (9,14,15,22), where authors have shown that the higher the wall corrugation amplitude, the earlier the vortex formation in the bulge region, that the vortex initially forms on the upstream portion of the bulge region, and that as the Reynolds number increases, the vortex core migrates toward the downstream boundary of the bulge region. These features of the base flow are consistent with the current results (see Fig.…”

“…At a ¼ 0. 3 Deiber and Schowalter 9 observed the onset of turbulence at Re ' 500 while for a ¼ 0.54 Nishimura et al 10 observed onset at Re ' 200. To our knowledge, there are only two pre-existing analyses of flow stability in corrugated pipes.…”

“…To compare with pulsatile flow, the mass-transfer rate for one wavelength, which is measured in the 9th wave section, is presented in Figure 3 respectively. A sudden change of Sherwood number is observed in the transitional flow regime attributed to the flow instability (that is, the presence of intermittent turbulent motion in the laminar flow), which is quite different from the Tollmien-Schlichting instability (Nishimura et al, 2003). In comparison with the result obtained for the straight-walled tube with the maximum diameter D max , shown by the dotted line, the Sherwood number for the wavy-walled tube is larger, particularly in the turbulent flow regime.…”

“…Steady flow experiment (P ‫؍‬ 0.0) Flow characteristics for steady flow in a wavy-walled tube have already been described in the previous study (Nishimura et al, 2003). To compare with pulsatile flow, the mass-transfer rate for one wavelength, which is measured in the 9th wave section, is presented in Figure 3 respectively.…”
