WebA lot of work has been done to predict the apparent diffusion coefficient in porous media. Carman (1939) has shown that, in porous rock, fluids must move on the average at about 45° to the direction of flow (Figure 3‑5). Hence, when fluid has traveled a net distance, L, it has traveled an actual average distance of about √2 x L. WebFeb 27, 2024 · In the case of the CC3 impeller, the method based on relative diffusion effectiveness calculated the same diffusion factor (1.40) as the design choice of the CC3 impeller. Additionally, the new method gives an optimum exit radius of 214.4 mm, with less than a 1.2 mm difference from the CC3 impeller design. As to the SRV2-O impeller, the …
