Annular falling film. Falling film reactors are commonly used in continuous photochemical processes. The example given in the figure below is for an advanced oxidation process. Solution inlets. O, Outlet Falling film 26 mm- Inner tube Immobilized TiO₂ particles UVA lamp Outer tube Ozone movement direction ← Stand 700 mm Solution outlet O, inlet a. Develop a shell balance for the falling film on the inner wall and obtain the velocity profile. The inner radius is R. (R+ 8) ² In (R) - -PB (R+ P² ln V. = pgR2 4μ [-] 2μ R b. Obtain the volumetric flow rate. 3 5) V = πpg | (R+8)ª 2 ln 1+ 1 + / -) - 2² ] + R ³²( R + 5)² μ 2 c. Can you derive an explicit expression for the film thickness, 6? (R+ Rª R 8
