Webdoublets, their diffusion coefficients can be determined by means of Eqs. (5) and (8). Finally, the dynamic shape factors, K, of the doublets can be calculated by means of Eq. (1) and the adjusted sphere factor by means of Eqs. (4) or (A6) with K, evaluated by a regression analysis with Eq. (2). Aerosols Webdiffusion coefficients plotted against the reciprocal of the absolute temperature yield a straight line in most of the cases, implying that over the temperature range, the diffusion coefficients can be expressed as: kT E o a D e (Equation 8.4) where D o denotes the diffusion coefficient extrapolated to infinite temperature and E a

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. WebPutting this together gives the classical diffusion equation in one dimension. ∂u ∂t = ∂ ∂x(K∂u ∂x) For simplicity, we are going to limit ourselves to Cartesian geometry rather than meridional diffusion on a sphere. We will also assume here that K is a constant, so our governing equation is. ∂u ∂t = K∂2u ∂x2.
