## 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

(a`Star-CCM+`

case definition file that initiates the solver for simulation 1)

**Simulation 2:**flow around a cylinder

download the following file: setupPost.java

(a`Star-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

(a`Jupyter NoteBook`

that contains the`python`

code needed to do the assignment) - Start
`Jupyter Lab`

: https://jupyter.org/try-jupyter/lab/ - Upload the
`Jupyter NoteBook`

in`Jupyter Lab`

- Go through the assignment step by step in
`Jupyter Lab`

. Write down answers to questions in the`Jupyter NoteBook`

. Derivations made using pen and paper or tablet can be included as photos/images in the`Jupyter NoteBook`
