Diffusivity parameter
WebJan 25, 2024 · The diffusivity of ethane in the STO is determined using the methodology developed in previous work (Ratnakar and Dindoruk 2016, 2024). Once the diffusivity parameter is determined from pressure-decay data, the compositional variation is analyzed by solving the 1-D transient diffusion model. WebThermophoresis. Thermophoresis (also thermomigration, thermodiffusion, the Soret effect, or the Ludwig–Soret effect) is a phenomenon observed in mixtures of mobile particles where the different particle types exhibit different responses to the force of a temperature gradient. This phenomenon tends to move light molecules to hot regions and ...
