Description
Bingham fluids are pastes that act as solids under light stress or pressure, but flow like viscous or viscoelastic liquids once the applied stress or pressure is stronger.
They are often made up of networks of particles or rope-like molecules. These constituents softly stick to each other, creating a gel-like solid. If the applied stress is too weak to unstick the constituents, the fluid remains solid. Once enough stress is applied to unstick the constituents (particles or rope-like molecules), the paste flows.
Blood is a common (and complex) Bingham fluid.
It takes a little time for things to stick to each other. Even tiny particles or polymeric molecules have to sort themselves into a geometry that maximizes contact to maximize sticking. This property puts a time frame on soft interactions, and creates a situation where a static complex fluid resists flow more than a moving fluid. So once the fluid is flowing, the stickiness may add to the effective friction of the fluid, but it is less than when the fluid is sitting still.
I have tried to capture some of the microstructural ideas and flow ideas in the details of the drawing. If you look carefully you can see some of the equations describing Bingham pastes and flows. Sorry if they are not all clear.
