Girona Docking and 3D-BT

As a continuation of the Internship of Summer 2022, in which we developed a docking station for the Girona AUV. we propose a new underwater marker that will be used in the docking process. So we aim to test the docking in this master thesis.

To achieve the goals of this thesis, we created various simulations. We began with Blender to simulate and test newly developed markers. Then, we used Blender to adapt the docking station from a CAD model into a 3D object for integration into Stonefish, a simulation software for underwater applications. With all necessary objects prepared, we developed a simulated environment to test and refine the docking process. Finally, we manufactured the required tools to perform docking tests in the ViCOROB test tank.

Jacketed Vessels

Jacketed vessels are containers used in industrial manufacturing and food production. These vessels use a steam input to heat the products inside, ensuring safe and effective cooking.

In this study, we used the four main methods of jacketed vessels: dimpled, two-layer, spiral, and piped. We created simulations for nine different models and, in the end, proposed enhancements for the simpler designs, as they are more cost-effective to manufacture. We developed 3D models of the vessels and used StarCCM+ to conduct finite element analysis based on mesh structures. Additionally, we applied mathematical models to calculate the improvements resulting from modifications to the jacketed vessels.

This project was recognized by Tripoli Syndicate of Engineers in the national competition for the Best Master’s Thesis in Mechanical Engineering. As a result, we won the first award for 2017.

Step Energy Harvesting Machine

The idea is to harvest the energy of the steps in malls and university to produce electricity.

To develop this design, we tested various mechanical and electrical methods. The final approach involved bending a piezoelectric material to generate sound waves. We incorporated multiple sensors and built a spring system with diodes to ensure one-directional current flow. The result was capable of directly powering multiple LEDs. However, to charge a battery, we needed an additional circuit to convert the low-current, high-voltage output for storage in batteries. The design included detailed engineering of both mechanical and electrical circuits.
