What is the difference between the stream function and the equation of the streamlines(if any)? cheers
A stream function is a mathematical function used to describe the motion of a fluid flow. It is a scalar quantity that is constant along a streamline. Streamlines, on the other hand, are imaginary lines that represent the direction of fluid flow at a given point. They are always parallel to the direction of the fluid velocity.
No, stream function and streamlines are not interchangeable. Stream function is a mathematical function while streamlines are graphical representations. They serve different purposes in describing fluid flow and cannot be used interchangeably.
Streamlines and stream function are useful in fluid dynamics as they provide a visual representation of fluid flow. They can help determine the path of fluid particles, identify areas of high and low pressure, and analyze the behavior of fluid flow in different scenarios.
Yes, the stream function is always constant along a streamline. This is because the stream function is defined as the ratio of fluid flow rate to velocity, which remains constant along a streamline. Therefore, the value of the stream function will not change along a streamline.
Yes, stream function and streamlines can be used for both laminar and turbulent flows. However, they may be more useful in laminar flows as the fluid flow is more predictable and follows a specific path. In turbulent flows, the fluid particles may move in a more chaotic manner, making it difficult to accurately represent the flow using streamlines and stream function.
