The flow behavior index, often denoted as 'n', is a parameter used to characterize the flow behavior of non-Newtonian fluids, indicating how the viscosity of a fluid changes with the rate of shear. This index plays a crucial role in determining whether a fluid behaves more like a Newtonian or non-Newtonian fluid, impacting its flow properties under different conditions. Understanding the flow behavior index helps in predicting how fluids will move and respond to external forces, which is essential for various applications in fluid dynamics.
