Slurry deposition velocity
WebbFor particles, the deposition velocity Vd is determined by the gravitational settling velocity (or sedimentation velocity Vs) and the inverse of the aerodynamic resistance Ra and the overall quasi-laminar resistance Rs.

WebbDeposition velocity is the velocity below which particles begin to deposit forming moving or stationary beds at the bottom of the pipe . This causes the flow to become unstable, and the pipe will eventually clog. Partial … Webb30 okt. 2024 · Coal-water slurry is one of the popular types of such compositions. Addition of the waste petrochemicals into the slurry allows decrease of the ignition delays of such composite for up to 27%. However, it has a non-trivial effect onto the atomization dynamics of the slurry making the size and velocity distributions of the aerosol more stable during …
