Question: What is laminar flow? What is turbulence? Answer: When a fluid flows through a pipe, its flow state can be classified as laminar or turbulent. Laminar flow occurs when the fluid particles move in layers always in a direction parallel to the pipe axis ； When fluid particles not only move forward along the axis of the pipe but also undergo irregular radial movements due to changes in flow velocity and direction, causing them to collide with each other and form vortices, this state of the fluid is known as turbulence.

When a fluid flows through a pipe, its flow state can be classified as laminar or turbulent; laminar flow occurs when the fluid particles move in layers always in a direction parallel to the pipe axis； When fluid particles not only move forward along the axis of the pipe but also undergo irregular radial movements due to changes in flow velocity and direction, causing them to collide with each other and form vortices, this state of the fluid is known as turbulence.
Laminar flow is a state of flow for fluids. When a fluid flows inside a pipe, its particles move in smooth straight lines parallel to the pipe axis. This type of flow is called laminar flow or steady flow; it is also referred to as straight-flow flow.
Turbulence is a state of flow in fluids. When the flow velocity is very low, the fluid flows in layers without mixing with each other; this is known as laminar flow, or also referred to as steady flow or sheet flow ；
#Laminar flow and turbulent flow are properties of fluid motion. When a fluid is in flow, if the trajectory of the fluid particles (which generally varies with the initial spatial coordinates x, y, z and time t) is a regular, smooth curve (with a straight line being the simplest case), such flow is called laminar flow; flow that does not possess this property is called turbulent flow.

When the flow velocity is very low, the fluid flows in layers without mixing with each other, a condition known as laminar flow； When the flow velocity increases significantly, the streamlines become indistinct, and many small vortices appear in the flow field; the laminar flow is disrupted, with not only sliding but also mixing occurring between adjacent flow layers. At this point, the fluid moves in an irregular manner, with component velocities perpendicular to the axis of the flow tube; such motion is known as turbulence, also referred to as chaotic flow, disturbed flow, or turbulent flow.
