Theories are developed for estimating thermo‐ and diffusiophoretic deposition of particles in liquid as well as gas phase heat and mass transfer equipment, operating under turbulent conditions. Simple expressions are obtained which give satisfactory agreement with experimental data. It is shown that the phoretic effects can lead to appreciable particle deposition, and the practical implications of this, such as heat exchanger fouling, are discussed. The simultaneous occurrence of these and other deposition mechanisms is also considered.
