WitrynaThe meaning of NEWTONIAN FLUID is a fluid whose viscosity does not change with rate of flow. A Newtonian fluid is a fluid in which the viscous stresses arising from its flow are at every point linearly correlated to the local strain rate — the rate of change of its deformation over time. Stresses are proportional to the rate of change of the fluid's velocity vector. A fluid is Newtonian only if the tensors … Zobacz więcej An element of a flowing liquid or gas will suffer forces from the surrounding fluid, including viscous stress forces that cause it to gradually deform over time. These forces can be mathematically first order approximated Zobacz więcej Water, air, alcohol, glycerol, and thin motor oil are all examples of Newtonian fluids over the range of shear stresses and shear rates … Zobacz więcej • Fluid mechanics • Non-Newtonian fluid Zobacz więcej
