Simulation of Flow of Fluid in Hot and Cold Pipe

General Information
1. The objective of the simulation:- Main objective of CFD analysis is following
a. Find the inlet and outlet temperature of hot pipe and cold pipe and their difference.
b. Find the inlet and outlet pressure of hot pipe and cold pipe fluid and their difference.
c. Find the inlet and outlet velocity of fluid in hot pipe and cold pipe and their difference.
d. Generate the graph of stream flow of fluid
e. Generate the graph of contour flow (Munson, 2007)
Methodology
We follow the following step to analyses the heat exchanger in CFD module of ansys in work
wench.
Step1. Generate 3d model in solid works software with given dimension.
Step 2. Start workbench of ansys software.
Step3. Used fluid flow (fluent)

Step 4: import the geometry or create the geometry then fill the martial like fluid inside
the pipe the re generate the geometry.
Step 5: shutdown the design modeller.
Step 6: start the mesh module
Setting the value of module
1. Defaults value like physics preference and relevance value.
