Webinar Recording: Rheology Tools: Identifying, Understanding, and Handling Data Artifacts

Viscosity is a calculated property and not directly measured. When the assumptions used to perform the viscosity calculation are violated, the value provided by the instrument is flawed. These errors are commonly referred to as artifacts. We discuss the artifacts that may be observed in rectangular slit flows, including:

• Shear induced heating
• Wall slip
• Yielding
• Turbulence
• Other inhomogeneities
