Impingement efficiency
Witryna1 gru 2015 · Two different configurations of the normal jet impingement test were implemented at distances of 5 mm and 25 mm. Fig. 1 shows the location of the boundary conditions. Schematics of both configurations are shown in Fig. 2 (a) and (b). The velocity magnitude at the inlet of both was chosen to be uniform with a value of 10 m / s.For … WitrynaV = impinging droplet mean mass velocity, m · s−1 V∞ = freestream droplet velocity, m · s−1 We n = Weber number based on impinging droplet normal velocity α = impact angle, deg β dep = collection efficiency β imp = impingement efficiency Δt = accretion time, s ϵ = sticking efficiency θ = angle of incidence, deg θ c = critical ...
