NACA 0012 is commonly used for the validation both numerical and experimental analysis. This analysis is also a fundamental knowledge in aerodynamics. Furthermore, there is large body of work to review that covers the NACA 0012. Some literature reviews have already been placed in the Computational Aerodynamics-1 module under Additional Journal folder of Assignment 2 folder. Please kindly read the journal papers and try to search other literature on the web.

You are asked to work as individual to simulate and analyse the validation of NACA 0012 under different flow conditions using ANSYS FLUENT 2021 R1 and wind tunnel.

You MUST attend the wind tunnel experimental in groups to get the data for the numerical study. You will be required to convert the excel data produced the wind tunnel experiment and it might be helpful to see the visual graph produce by manometer.

The geometry, domain, and mesh of a NACA 0012 will be guided by the research from journal papers and that is your entirely your choice.

Assuming that the fluid is air, you will need to find the values of dynamic viscosity and density of air (given a constant temperature). The value can be taken from the Engineering toolbox website or other sources such as the weather station located in the wind tunnel room (this must be referenced) and it should be based on room temperature recorded on the weather station. You must decide which air temperature your simulation will be based on.

The NACA 0012 profile can be downloaded from number of websites (e.q. Airfoiltools.com) and MUST be imported and modelled using the ANSYS FLUENT modeller. All simulations MUST BE 2D (two-dimensional simulations only). You should read and follow the guidance in every step to ensure that you will understand the work require for the assignment before attempting your assignment.

Three analyses need to be conducted based on 0, 5 and 15 degrees of Angle of attack with pressure based and steady state as the standard simulation. As the wind tunnel will produce maximum 32 m/s velocity therefore you will apply this inlet velocity in the simulation and calculate the Reynolds number and the domain size chosen must base on research. The turbulent modelling will be K-? turbulent model.

The mesh size suggested would be up driven by the research that you are reading.

Full analysis using Reynold number, as specify previously, are needed after the optimum mesh setup is chosen. You will be required to produce graph of pressure coefficient, Velocity, coefficient of drag and coefficient of lift.

Your graphical result should have pressure, velocity both vector and contour.

You will need to discuss the comparison and validate between the CFD simulations with experimental data together with the literature review.

Based on your work, write a full technical report subjected to a 3000-word limit and submit the ANSYS project file.

Guideline for the report structure

The structure may include:

- Cover page including name

- Abstracts.

- Contents including figure list and table list.

- Introduction.

- literature review.

- CFD setup.

- Discussion result.

- Critical analysis

- Conclusions.

- Recommendations.

- References

- Appendices.

The BOLD wording is where the word count will be applied.

Detail requirement:

  • Third person must be used in the report. Since this is a standard and technical report therefore the word I, we, they and another first person IS NOT allowed.
  • Equation edition or similar tools for typing formulas MUST be used.
  • Maximum word 3000 for the report.
  • Correct citation of references and proper numbering of equations and figures.
  • References MUST BE provided and follow Harvard style or IEEE referencing system.
  • The final report needs to be submitted through the e-submission point within the module blackboard before the deadline under ASSESSMENT folder.
  • DO NOT MISS THE DEADLINE FOR THIS E-SUBMISSION.

Detailed requirement:

  1. The Introduction section should focus on relevant background information, relevant literature, and real-life applications to highlight current research, challenges and importance of this topic.
  1. The Method section should present how to select the physical models,computational domain, meshing details and boundary conditions. It should include the theory/formulae/any hand calculation if appropriate.It should cover all information, which enables other people to reproduce your work.
  1. The Results section should detail the numerical simulation results. You need to use geometric displayer, mesh displayer, scalar displayer, vector displayer and streamline displayer to show your results. It is necessary to use fluid dynamics concepts and principles correctly to explain the results. The plot diagram will need to be required included on the report.

(HINTS: DO NOT INCLUDE IMAGES ONLY, YOU ALSO NEED DESCRIPTIONS/EXPLANATIONS; DO NOT USE ANSYS FLUENT SCENES AS SUBSECTION TO ORGANISE RESULTS).

  1. The Discussion and Critical analysis sections should demonstrate your critical analysis about the CFD technique, fluid dynamics principles, cross comparison with published data, and its implication for applications. You may investigate the effect of certain important factors under different flow conditions
  1. The Conclusion section should briefly summarise what you have obtained from this simulation exercise.
  1. Reference MUST be provided and follow Harvard style or IEEE referencing system.
