Rheology is in action all around us, from asphalt that doesn’t melt on a hot day to perfectly melting chocolate. Foods, motor oils, cosmetics and pharmaceuticals depend on rheological data to perform as expected. This field of science examines the behavior of fluids and materials at different pressures and temperatures, specifically measuring how they flow. Rheology makes products we use every day better, easier to use and safer. You can thank rheology for ketchup that’s not runny and lotion that spreads smoothly on your skin.

Listen now as SwRI Sr. Research Engineer Dr. Carlos Sanchez discusses rheology, the “go with the flow” science that’s everywhere.
