OA was measured at 298 K, for comparison with the literature, and MO was measured at several temperatures, including 263 K, 298 to 318 K in 10 K steps, and 338 K. Dynamic viscosity measurements of MO were performed on an AR 2000 Rheometer (TA Instruments), on a double-gap Peltier cylinder system in steady-state flow mode, in the temperature range of 288 to 358 K.
The processability of MFC/LS/CP slurries by 3D printing was examined by rheological tests in both steady flow and thixotropic modes.
It can also be found that the steady flow firstly changes the mode shape of the cantilever and consequently affects the energy dissipation.
In conclusion and according to the study results the pulsatile tube was successfully capable of transforming a conventional CPB and/or CAD steady flow into a pulsatile perfusion mode, with nearly physiologic pulse pressure and lower energy losses.
Results show that a stable device operation is achieved (i.e. evaporator wall temperatures can reach a pseudo-steady-state) only when a circulating flow mode is established superimposed on local pulsating flow.
In vitro, as resumed in Table 1 and Figures 3, 4, and 5, globally, mean flow pressures at P5 were significantly better in the pulsatile mode (P) compared with steady flow (NP); mean P5 were 31,8 ± 1 versus 30,8 ± 0,5; 40,3 ± 0,5 versus 39,3 ± 0,5; and 44,8 ± 0,5 versus 43 ± 0,00 mmHg with tube position in circuits I, II, and III, respectively (P < 0.001).
A dynamic experiment with four stages (EPA1 EPA4 in Table 1) was conducted at the U.S. EPA Researchh Triangle Park, NC) 14.5-m Teflon chamber operated in a flow mode to produce a steady-state condition.
When operated in an open flow mode, the model successfully predicted steady MIB removal rates with time.
In this method, a periodic pressure oscillation signal which frequency equals to the first acoustic mode is superimposed on a steady flow at the head end of the chamber.
