Learning Outcomes
On successful completion of this assignment, the student should be able to:-
1. Critically evaluate the concepts of fluid mechanics.
2. Critically evaluation of the principles of CFD (Computational Fluid Dynamics) to the requirements of the mechanical industry.
The Brief
Part 1 modelling
You will be asked to model, research and analyse the wing with Star CMM+ using variation conditions.
The wing could be modelled on the SolidWorks and Imported to Star CMM+ or alternatively it can be drawn direction to the Star CMM+.
The wing sketch would be provided and the student needs to modify accordingly to meet student's own scenario.
Each student will have different scenario and depends on their unique student ID based on the rules below:
The rules:
If you student ID number is 100123456 therefore:
• The last digit will determine the NACA profile camber:
o 1 - 2 will use NACA 1 series
o 3 - 4 will use NACA 2 series
o 5 - 6 will use NACA 3 series
o 7 - 8 will use NACA 4 series
o 9 - 0 will use NACA 5 series
• The second last digit will determine the maximum chamber position
o 1 - 2 will use Max Camber 10%
o 3 - 4 will use Max Camber 20%
o 5 - 6 will use Max Camber 25%
o 7 - 8 will use Max Camber 35%
o 9 - 0 will use Max Camber 40%
• The third last digit will determine the thickness
o 1 - 2 will use Thickness 10%
o 3 - 4 will use Thickness 15%
o 5 - 6 will use Thickness 20%
o 7 - 8 will use Thickness 25%
o 9 - 0 will use Thickness 30%
• The fourth last digit will determine the angle of attack
o 1 - 2 will use 1 degree angle of attack
o 3 - 4 will use 1.5 degree angle of attack
o 5 - 6 will use 1.75 degree angle of attack
o 7 - 8 will use 2 degree angle of attack
o 9 - 0 will use 2.5 degree angle of attack
Your task will be
• To conduct a research on the Wing analysis using CFD on journal paper or other sources (WIKIPEDIA is NOT allowed)
• To create the wing profile based on your student ID
• To prepare the wing profile based on your scenario
Part 2 CFD setup and analysis
Your task will be:
• To create a setup for the wing using Star CMM+
• To run the simulation where the velocity is 90 km/h
You need to consider the following:
• The mesh size (geometry preparation)
• The physics setup
• Boundary condition
• Solver settings
• Post processing
• Is there any better way to improve your setting?
Hint: you really need to consider more scenarios rather than stick to one solution
Part 3 Result and critical analysis
Please print and discuss all the results achieved, based on:
a) Geometric displayer
b) Scalar displayer
c) Vector displayer
d) Streamline displayer
Hint: Please conduct a critical analysis - do NOT just discuss the images
Part 3 Conclusion
Flow analysis, using Computational Fluid Dynamics, has been widely used in many engineering disciplines. Based on your results, discuss the following points:
a) The method of simulation construction during the analysis.
b) Possible mistakes that could be made when conducting simulation.
c) Conclusion
d) Recommendations for the system design to achieve the aim and objectives set
