Pitot Tube Design and Wind Tunnel Performance Analysis

• Analysed and refined Pitot tube designs to improve airflow measurement accuracy and performance in wind tunnel testing applications.
• Applied aerodynamic principles and engineering analysis to evaluate measurement performance, identify potential design improvements, and support more reliable experimental testing.
• Used MATLAB to process experimental data, analyse results, and assess Pitot tube performance, supporting evidence-based engineering decisions.
• Interpreted technical data and prepared engineering reports documenting findings, evaluating potential issues, and recommending design improvements.
• Collaborated with team members to troubleshoot technical challenges, coordinate project tasks, and deliver project objectives.
• Applied knowledge of aerodynamics, control systems, and propulsion to strengthen understanding of aircraft measurement systems and practical engineering applications.

• Designed a low-cost, solar-powered wireless monitoring system for early detection of bridge fatigue, integrating an ADXL355 MEMS accelerometer, ESP32 microcontroller and LoRaWAN communication to enable remote structural vibration monitoring.
• Determined the sampling rate using the Nyquist criterion and evaluated analogue-to-digital conversion (ADC) resolution, Fast Fourier Transform (FFT) frequency resolution and wireless transmission time to support reliable vibration analysis while minimising power consumption.
• Performed a root-sum-square measurement uncertainty analysis to assess compliance with accuracy requirements, and calculated the total cost per installed monitoring node to evaluate affordability and scalability for bridge monitoring applications.
• Assessed the power budget, solar charging capacity and communication duty cycle to support energy-efficient operation and inform the system’s suitability for long-term remote deployment.

• Designed a hand-cranked wind turbine model combining a gear train, cam-follower, lever and slider-crank mechanisms.

• Carried out kinematic, torque and energy calculations and ran a SolidWorks motion simulation to verify uniform rotation and cam-follower displacement.

• Assessed shaft torsional stress and crank bending stress against PLA material limits, recommended a thicker crank, and validated the concept with a cardboard prototype.

• Flood mitigation trade-off analysis (Fitzroy River): weighted-criteria comparison of drainage options (channel ranked first) and prevention options (levees and dikes ranked first).

• Water temperature monitoring instrument: technical proposal for a solar-powered floating instrument to record surface temperature of water deposits in an IGNIS bushfire research scenario.

• Vibration sensor lab: sensor data analysis in technical report.

• Bridge design: load analysis and structural sizing. HVAC design project.
