Laminar flow is a type of fluid flow characterized by smooth, orderly movement of particles in parallel layers, with little to no mixing between the layers. This type of flow occurs at low Reynolds numbers and is commonly seen in small pipes, blood vessels, and other confined spaces. Laminar flow is important in various engineering and scientific applications, such as in the design of microfluidic devices, heat exchangers, and chemical reactors. Studying laminar flow involves the analysis of fluid dynamics principles, such as viscosity, pressure gradients, and flow rate, to better understand and predict the behavior of fluids in different systems.
