Two Dimensional Flow of Ideal Fluids

In the study of fluid mechanics, the two-dimensional flow of ideal fluids is an important concept. Here are some key points to consider:

Stream Function and Potential Function

- The stream function is a mathematical function that describes the motion of a fluid in two dimensions. It is used to determine the velocity components of the fluid and is related to the mass flow rate.
- The potential function is also a mathematical function that describes the motion of a fluid in two dimensions. It is used to determine the pressure distribution of the fluid and is related to the total energy of the fluid.
- In two-dimensional flow of ideal fluids, the stream function and potential function are related to each other through the Laplace equation.

True Statement

The true statement for two-dimensional flow of ideal fluids is:

- Stream function will exist but potential function may or may not exist.

Explanation

- In two-dimensional flow of ideal fluids, the stream function always exists. This is because the stream function is related to the mass flow rate and is a fundamental property of the fluid motion.
- However, the potential function may or may not exist depending on the flow conditions. For example, in irrotational flow, the potential function exists and is related to the pressure distribution of the fluid. But in rotational flow, the potential function does not exist because there is no unique pressure distribution.
- Therefore, the correct answer is option 'D' - Stream function will exist but potential function may or may not exist.
