Fluid Dynamic Gauging for Studying Early Stages of Swelling of Fouling Deposits

A new variant of the fluid dynamic gauging technique for determining thickness soft fouling layers in situ and real time is reported. The sideways (SiDG) device allows measurements to be made shortly after a deposit layer contacts solution, allowing processes such as swelling characterized accurately. Two applications are reported: (i) cleaning, monitoring change complex food soil when it contacted with aqueous solutions at different temperatures, pH surfactant content, (ii) fouling, thickness, thermal conductivity strength deposits generated from whey protein on heated stainless steel substrates. evolution resistance indicates that significant aging takes place during test, which confirmed by changes properties measured SiDG device.
