Webinterfacial shear rheometer. Such routines use a second order centered finite difference (SOCFD) discretization scheme, in both the vertical and radial coordinates, for the velocity field in the bulk fluid subphase and a first order forward finite difference (FOFFD) scheme in the vertical coordinate WebInterfacial rheology is a branch of rheology that studies the flow of matter at the interface between a gas and a liquid or at the interface between two immiscible liquids. The measurement is done while having surfactants, nanoparticles or other surface active compounds present at the interface. Unlike in bulk rheology, the deformation of the ... WebApr 4, 2024 · Interfacial Rheology. Interfacial rheology experiments were performed using a DHR-3 TA Instruments rheometer, with a Double-Wall Ring (DWR) geometry. The oil/water interface was found by performing an axial measurement before every experiment. Oscillation sweeps were made at room temperature using a frequency of 1 rad s −1. samsung scx 4623fw scanner software
