FAQs on Stream Function Video Lecture - Fluid Mechanics for Mechanical Engineering

1. What is a stream function?

Ans. A stream function is a mathematical concept used in fluid dynamics to describe the flow of a fluid. It is a scalar quantity that maps each point in a fluid flow field to a value, representing the flow velocity perpendicular to a given surface.

2. How is the stream function related to fluid flow?

Ans. The stream function is related to fluid flow as it helps visualize and analyze the flow patterns. By plotting the streamlines, which are curves that are everywhere tangent to the velocity vector, one can gain insights into the direction, speed, and behavior of the fluid flow.

3. What are the applications of stream functions in engineering?

Ans. Stream functions have several applications in engineering, particularly in fluid mechanics and aerodynamics. They are used to analyze and design airfoils, study heat and mass transfer, model flow in pipes and ducts, and predict fluid behavior in various engineering systems.

4. How is the stream function calculated for a two-dimensional flow?

Ans. In a two-dimensional flow, the stream function can be calculated using the continuity equation, which relates the partial derivatives of the stream function with respect to the coordinates. By solving this equation, the stream function can be determined and used to understand the flow characteristics.

5. Can the stream function be used for three-dimensional flows?

Ans. The stream function is primarily used for two-dimensional flows, where the flow velocities only vary in two directions. For three-dimensional flows, additional mathematical concepts, such as the velocity potential function, are required to fully describe the flow field. However, a modified form of the stream function, known as the stream function per unit volume, can be used to analyze three-dimensional flows.
