Shockwave Location Detection in a Converging-Diverging Duct

Project Overview

This project focuses on developing a MATLAB tool to evaluate the location of a traveling shockwave in a converging-diverging (CD) duct. The tool allows users to input various parameters, simulate the conditions within the duct, and visualize the results.

Features

• User-Defined Inputs:
  • Exit pressure, inlet pressure, temperature, and Mach number.
  • Fluid properties (specific heat ratio ( k ) and gas constant ( R )).
  • Geometric configuration of the duct (length of each section, inlet, throat, and outlet diameters).
  • Wall function options: linear or quadratic.
• Unit Flexibility:
  • Accepts inputs in both SI and Imperial units.
• Outputs:
  • Pressure, temperature, velocity, and Mach number before and after the shockwave.
  • Visualization of these properties along the duct.
  • Geometry plot of the CD duct.

Outputs

1. Plots:
   • Mach number, pressure, and temperature distributions along the duct.
   • Duct geometry visualization.
2. Tabular Data:
   • Key parameters before and after the shockwave.

Team Contributions

This project was completed as part of a group effort. Each member played a critical role in its success:

• Omar (Team Leader): Responsible for developing the GUI and integrating the code.
• Loka: Focused on validation of the results.
• Shady: Developed unit conversion utilities and verified simulation results.
• Hamza: Developed the algorithm for detecting teh shockwave using iterative methods.
• Dr. Omar Abdulaziz: Guided the project and provided valuable insights throughout the development process.

Bonus Feature

The tool also includes a bonus feature to plot fluid properties and Mach number variations throughout the CD duct, enhancing the understanding of flow dynamics.

Repository Contents
