Numerical simulation of boundary layer flows
In this assignment you will use a commercial Computational Fluid Dynamics (CFD) software called Star-CCM+. Two different simulations will be done. The first involves flow over a flat plate and you will extract data from the CFD simulation to compare with the analytical/empirical formulations for laminar and turbulent boundary layers. In the second task you will simulate the flow over a cylinder and compare the simulated flow field with data from an experiment.
- Read the instruction document (MTF053_CA2.pdf)
- Follow the detailed guide provided in this document to do two
Star-CCM+simulations.
Simulation 1: flat plate boundary-layer flow
download the following file: MTF053_CA2_Task-1.sim
(aStar-CCM+case definition file that initiates the solver for simulation 1)
Simulation 2: flow around a cylinder
download the following file: setupPost.java
(aStar-CCM+Java macro that sets up the postprocessing for simulation 2)
- Perform tasks and answer questions related to the two simulations
- Download the following file: MTF053_CA2.ipynb
(aJupyter NoteBookthat contains thepythoncode needed to do the assignment) - Start
Jupyter Lab: https://jupyter.org/try-jupyter/lab/ - Upload the
Jupyter NoteBookinJupyter Lab - Go through the assignment step by step in
Jupyter Lab. Write down answers to questions in theJupyter NoteBook. Derivations made using pen and paper or tablet can be included as photos/images in theJupyter NoteBook. - To download your modified
Jupyter NoteBook, right click on the notebook file in the file tree on the left side of theJupyter Labuser interface and click on download in the drop down menu.
