Application of Non-Newtonian fluid
Speed bump: Application of Non-Newtonian Fluid What is Fluid? A F luid is a liquid , gas , or other material that continuously deform ( flows ) under an applied shear stress , or external force. They have zero shear modulus , or, in simpler terms, are substances which cannot resist any shear force applied to them. The different properties of fluid are viscosity, Temperature, Density, Pressure. Types of fluid according to Viscosity Behaviour. 1. Newtonian fluid - The fluid which viscosity remain constant irrespective of shear applied at constant temperature. 2 . Non Newtonian fluid - The fluid which viscosity changes with respective to shear applied. Its means it has non linear relationship between shear rate and shear stress. Newton's law of Viscosity It states that 'the shear stress is directly proportional to velocity gradient'.It defines the relationship between the shear stress and shear rate of a fluid subjected to a mechanical stress. The ratio o
