WebJan 6, 2024 · The Cunningham slip correction factor, C c , which corrects for reduced the drag force on particles in gas flow, is calculated as (Allen and Raabe, 1985). Under the consideration of slip flow boundary condition (at negative pressures), the Kuwabara hydrodynamic factor shall also be a function of Knudsen number.

WebThe Cunningham slip correction factor allows predicting the drag force on a particle moving a fluid with Knudsen number between the continuum regime and free molecular flow. The drag coefficient calculated with standard correlations is divided by the Cunningham correction factor, C given below. WebThe Davies parameterization gives a Cunningham slip correction factor that is, on average, 2.5% larger than the other parameterizations over the diameter range 50 − 500 nm that is relevant to our work, and the retrieved effective densities using the Davies parametrization are approximately 0.3% less than the values calculated using the other ... how do i fix the print spooler in windows 10

Approximation of most penetrating particle size for fibrous …

WebThe slip correction factor is used to calculate the friction factor. Thus, the slip correction factor is about unity (1) for larger particles (Kn -> 0). Its behavior on the other end of the spectrum (smaller particles; Kn -> inf) is more nuanced, though it tends to scale linearly on a log-log scale, log Cc vs log Kn. WebCunningham Correction Factor For very small particles, when the particle size becomes comparable with the gas mean free path, slip occurs and the expression for drag must … WebFrom an optical point of view, we have to consider the volume equivalent diameter D ve of the particles, we must therefore convert the size distribution in Figure 1 from the following relationship: (4) D v e = D m C (D v e) χ C (D m) (4) with C(D ve) the Cunningham slip factor of volume equivalent diameter. how much is tax on goods
