Limin Song, Julio D Lobo, Glen B Brons, San Chhotray, Himanshu M Joshi, George A Lutz: Mitigation of in-tube fouling in heat exchangers using controlled mechanical vibration. ExxonMobil Research and Engineering Company, Glenn T Barrett, November 23, 2010: US07836941 (23 worldwide citation)

Fouling of heat exchange surfaces is mitigated by a process in which a mechanical force is applied to a fixed heat exchanger to excite a vibration in the heat exchange surface and produce shear waves in the fluid adjacent the heat exchange surface. The mechanical force is applied by a dynamic actuat ...
