Explain four different types of fluid behavior: Newtonian, shear thinning, shear thickening, and Bingham plastic.Describe the similarities and differences between elastic solids and viscous fluids.Understanding fluid behavior can help engineers to select the best fluid to operate in a device or to design devices that are able to efficiently and harmlessly operate in environments that contain fluids.Īfter this lesson, students should be able to: Thus, it is important for engineers to understand how fluids behave under various conditions. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers often design devices that transport fluids, use fluids for lubrication, or operate in environments that contain fluids, such as engines, printers and pacemakers.
In addition, fluid material properties such as viscosity are introduced, along with the methods that engineers use to determine those physical properties. Several types of fluid behaviors are described-Bingham plastic, Newtonian, shear thinning and shear thickening-along with their respective shear stress vs. Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids.
