WebNov 12, 2024 · What is fouling? The most common definition of fouling in relation to heat exchangers is the deposition and accumulation of … WebMar 26, 2024 · A fouling layer forms when the particle deposition rate is higher than the removal rate. Technically, the opposite case of a high removal rate can be used to clean a soiled surface [ 6 ]. This higher removal can be achieved by increasing the shear stresses through increases in the fluid velocity and the use of surface structuring.
