Question

What different between 'flow analysis using control volume method' and 'flow analysis using differential method'?

Answer 1

Answer:

control volume

• control volume is used to determine the flow characteristics of  complex shape like turbine and compressors

differential approach

• it is carried out by considering infintely small region for fluid analysis.

Explanation:

control volume:

• control volume is used to determine the flow characteristics of  complex shape like turbine and compressors
• it is used to determine the flow velocity within in the boundaries of control volume.
• it can also used for force analysis for flow.
• one main disadvantage of control volume is that it doesn't provide detail information about stress and pressure variation.

differential approach:

• it is carried out by considering infintely small region for fluid analysis.
• solution of the fluid analysis is in the form of differential equation
• it provide detail information about the flow.
