👉 The Robert fluid, also known as the Robert-Bernstein fluid, is a theoretical viscous fluid that was proposed by physicist Robert H. Bernstein in 1946 to explain the anomalous viscosity observed in certain biological systems, particularly blood flow. This fluid is characterized by its unique property of exhibiting both shear-thinning and non-Newtonian behavior, meaning its viscosity decreases with increasing shear rate. This behavior is crucial for blood flow in narrow capillaries, where high shear rates are common, allowing the fluid to thin and facilitate smoother flow. The concept of the Robert fluid has been influential in understanding the complex dynamics of biological fluids and has implications for medical research, especially in the fields of hemodynamics and vascular biology.
