| Description
| - The wall shear stress is determined at the surface of a plane ceramic ultrafiltration membrane in a tangential ultrafiltration module. In a first time, the shear stresses are determined at the surface of a plate of Plexiglas mimicking a membrane and at the plane membrane surface without fouling particles with the aim to investigate the influence of permeation. In a second time, the wall shear stress is determined at the surface of the plane membrane during the ultrafiltration of a suspension of spherical no compressible particles inducing a deposit at the membrane surface. In order to study the influence of the foulant, two concentrations of particles were used for the experiments. The values of the mean wall shear stress and its fluctuations (turbulent intensity rate) were measured by using an electrochemical method. 20 microelectrodes, on which an electrochemical reaction occurs, are mounted flush to the plate of Plexiglas and to the surface of the membrane to determine the maps of shear stress and

- Střihové napětí na povrchu ploché keramické ultrafiltrační membrány je bylo měřeno v ultrafiltračním modulu. V prvním případě bylo střihové napětí měřeno na desce z plexiskla, které nahrazovalo membránu, a na povrchu deskové membrány bez přítomnosti částic v kapalině s cílem prozkoumat vliv permeace. Ve druhém případě bylo střihové napětí měřeno na povrchu membrány v průběhu ultrafiltrace suspenze obsahující sférické nestlačitelné částice, které vytvářely na povrchu membrány filtrační koláč. Pro studium vlivu množství depozitu na membráně byly použity dvě suspenze s různou koncentrací částic. Pro stanovení střihového napětí a jeho fluktuací (intenzita turbulence) byla použita elektrochemická metoda. 20 mikroelektrod, na kterých probíhala elektrochemická reakce, bylo umístěno na povrchu membrány a na povrchu plexiskla k určení střihového napětí a intenzity turbulence. Měření se provádělo pro dva různé distributory zajišťující přívod kapaliny do modulu. Práce ukazuje, že vlivem permeace membrány (cs)
