Figure 4: 𝑥 𝑦 cross-sections of simulated fluid dynamic under steady-state conditions of the reactor used for the photocatalytic test (flowing conditions). (a) 𝑉 i n = 32.4 L h−1, (b) 𝑉 i n = 4.2 L h−1. The cross-section follows the longitudinal symmetry and is focused on the inlet gas chamber and a portion of the channel containing the photoactive tile.
