Flow analysis over a cylinder using ICM CFD

Published on 14 Jun 2021. Written by Gurudutt

ICEM is a software developed by ICEM CFD engineering which provides classy geometry tools for mesh generation, pre-processing and mesh optimization tools. It is used for manufacturing applications such as computational fluid dynamics and mechanical analysis.

ANSYS ICEM CFD software supports a wider range of direct CAD boundaries and geometry, Components from diverse formats can simply be combined within one meshing assembly.

Fluent software contains the extensive, physical modeling abilities needed to model flow, turbulence, heat transmission and reactions for industrial applications.

Fluent does the following functions:

It provides a complete, single-window solution within Fluent.
Streamlines the Fluent workflow for generating a mesh from imported CAD.
Removes barriers for common tasks that frustrate users.

Procedure:

Run ICM CFD
Save the project
Go to geometry- create a point
Explicit location input as 0, 0, 0 for x, y, z-axis respectively
Go to Create/modify curve option- give input start angle as 0 degrees and end angle as 360 degrees.
Select create point - Give explicit location input as -5, 5, 0 and 10, 5, 0 for x, y, z-axis respectively.
Go to the constraints-select inlet of the cylinder and select vertical lines.
Select the axis of cylinder and select horizontal lines.
Go to dimensions- Give the required dimensions for inlet, outlet, axis, and wall.
Go to the concept- Select the surface.
In the tree outline-Select surface in the XY plane.
Go to base objects and apply the surface selected.
Now generate the geometry.
Go to the mesh option.
Right-click on mesh option- select insert-sizing.
In detail of sizing select geometry and apply after selecting all the 4 edges of the cylinder.
Give a number of divisions as 100 and generate the mesh.
In-tree page- Select solver as Pressure based.
Select velocity formulation as Absolute.
Select time- Steady.
Select 2D space- Axisymmetric (only for 0degree).
Click on the model- Select viscous as K epsilon (2 eq) & press done.
Click on materials-Select Air as fluid and Aluminium as solid.
Click on cell zone conditions- Select operating conditions and see that operating pressure is 101325Pa.
Click on boundary conditions-Select inlet-velocity inlet- 100m/s.
Select outlet- outlet pressure (gauge pressure as 0 itself) and press done.
Click on reference value- Compute from the inlet.
Click on initialization- Select standard initialization and compute from the inlet and initialize.
Click on run calculation and calculate for 1000 iterations (till when the curve converges) and calculate.
Go to results- Insert contour
Go to geometry – For domain select all domains.
For location select periodic 1.
For variable select Velocity.
For Range select global and apply.
Result is displayed.
Go to Function calculator- In function select MassflowAve.
For location select outlet and calculate.
Now to calculate pressure, mass flow average of pressure on the outlet, velocity, force- Go to function and select respective functions.
