I've a question about how to define the diffusion coefficient of a certain material in CFX please? Because I want to simulate the diffusion between two liquids in a domain. I haven't found any option that we can plug into the value of diffusion coefficient ...

Using electrical conductance measurements on the vitreous humor, Maurice (1957) estimated the diffusion coefficient for Na in the vitreous humor to be 90% of that for isotonic water at the same temperature, and so the diffusion coefficient for Na24 could be estimated as 1.7 × 10−9 m2/s....

Although diffusion-weighted imaging (DWI) is useful for differential diagnosis between lung cancers and benign pulmonary nodules and masses (BPNMs), it is difficult to differentiate pulmonary abscesses from lung cancers because pulmonary abscesses show restricted diffusion. With this research we will pr...
This parameter indirectly influences the thickness of the diffusion layer, leading to a consequent variation in the ip values: the longer the IT, the lower the ip. Since IT has no evident effect on the peak width, the resulting ip/W1/2 ratio decreases at the increasing IT (Fig. 2f, red...
Finally, we also predict the spin diffusion length (ls) of pristine CsPbBr3in the low-density limit, which sets the upper bound oflsat differentT. We use the relation{l}_{s}=\sqrt{D{\tau }_{s}}, whereDis diffusion coefficient obtained using the Einstein relation, with carrier mobility...
Indeed, diffusion at high temperature is driven by the random walk of the particles. Cooling lowers the diffusion constant by decreasing the velocity and the mean free path close to interatomic separation. Below a given temperature, collective excitations (e.g., sound) begin to operate. In a ...
