Flow analysis of aerofoil using ICM CFD

Published on 18 May 2022. Written by Gurudutt

An airfoil-shaped body moving through a fluid produces an aerodynamic force Some important constraints to describe an airfoil's shapes are its camber and its thickness.

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.

 

Procedure:

• Run ICM CFD
• Save the project
• Import formatted data points of NACA airfoil
• Go to geometry- create a point
• Explicit location input as 0, 0, 0 for x, y, z-axis respectively
• Create the block for airfoil by giving the required dimensions.
• Go to dimensions- Give the required dimensions.
• Go to the concept- create the surface
• 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 block
• 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.
• The 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.
