Heterogeneous Vapor Condensation in Boundary Layers
- Conference date: 16–20 September 2008
- Location: Psalidi, Kos (Greece)
We consider heterogeneous condensation of vapors mixed with a carrier gas in stagnation point boundary layer flow near a cold wall in the presence of solid particles much larger than the mean free path of vapor particles. The supersaturated vapor condenses on the particles by diffusion, particles and droplets are thermophoretically attracted to the wall. We sketch three asymptotic theories of the condensation process, calculate the flow‐induced shift in the dew point interface, vapor density profile and deposition rates at the wall, and compare them to direct numerical simulation.
