Wind Tunnel Experiment (Enhanced MATLAB Script)

This enhanced MATLAB script automates data analysis and visualization for a wind tunnel laboratory experiment.

Overview

This enhanced MATLAB script automates data analysis and visualization for a wind tunnel laboratory experiment. It processes pressure port measurements, computes airspeeds, generates contour maps, and produces key discussion points for engineering reports.

This version improves upon standard lab scripts with:

✔ Robust error handling & data validation

✔ Comprehensive visualizations (scatter plots, contour maps)

✔ Automated discussion points for lab reports

✔ Saving results with timestamped .mat files

Features

🔹 Data Import with Error Handling – Reads Excel sheets, validates existence, and provides informative error messages.

🔹 Port Geometry Visualization – Displays pressure port layout with labeled positions.

🔹 Unit Conversions & Constants – Fully documented constants for unit consistency.

🔹 Air Density Calculation – Uses real gas law with error checks.

🔹 Dynamic Pressure & Velocity Maps – Contour plots of pressure/velocity distributions for different test conditions.

🔹 Physical Validations – Handles invalid ports (e.g., Port #7) gracefully.

🔹 Automated Key Findings – Generates lab discussion points on temperature effects, flow uniformity, and probe anomalies.

🔹 Result Saving – Automatically saves processed data to .mat files with timestamps.

Requirements

• MATLAB R2020a or later (tested on R2025a)
• Excel file: Lab 2 Data 2025SP_UPDATED.xlsx
• Must contain sheets: "0 in H20 Test", "2 in H20 Test", "5 in H20 Test"
• Data ranges: B3:AL602 for pressure ports, AK3:AK602 for static ports
