Webinar Series by Netzsch: Yield Stress Unlocked - Exploring the Science and Applications of Complex Fluids
Netzsch is offering a webinar series on yield stress fluids.

Yield stress fluids are common in daily life and industry. Examples are many: toothpaste, mud, lava, cement, foams, mayonnaise, hair gel, chocolate, and more. Their archetypal feature is a dual response to applied stress: below a critical threshold (the yield stress) they behave like solids, while above it they flow like liquids. The flow characteristics of such materials are difficult to predict, as solid-like and liquid-like regions are generally not known a priori. These complexities, together with their wide range of applications, have been fascinating researchers across mathematics, chemical engineering, and fluid mechanics.

In this six-part webinar series, we explore the complex rheology of yield stress fluids and how it governs flow, stability, and performance across diverse processes and applications. The series brings together leading researchers from around the world—UBC (Canada), Cal Poly (USA), Strathclyde (UK), TU Delft (Netherlands), and ULaval (Canada)—to share practical methods and case studies spanning oil well cementing, gas emission from ponds, bioprinting, sustainability-driven materials, particle manipulation, and multiphase flows of yield stress fluids.
