Resume Pertemuan 1 (26/05/2023)

Pada pertemuan pertama Metode Numerik yang diampu Pak DAI, kita belajar tentang conscioussness in learning. Consciousness atau kesadaran merupakan kemampuan individu untuk menyadari dan mengalami dunia di sekitarnya. Kali ini, Pak DAI mengimplementasikan consciouscness kedalam penyelesaian operasi matematika. Kita selalu berasumsi bahwa matematika adalah sesuatu yang eksak, namun ada kasus dimana hasil operasi tersebut tidak pasti. Disitulah kesadaran kita sebagai manusia digunakan, dimana kita harus ingat hanya Tuhan yang memiliki kebenaran mutlak. Kita juga ditugaskan untuk mendesain dan optimasi penyimpanan hydrogen bertekanan dengan kapasitas 1 L dan tekanan 8 bar.

Week 1

In this project, I used the help of AI to guide me in designing and optimizing a hydrogen storage system. I used ChatGPT in helping me outline the process and here is its response.

To design and optimize a pressurized hydrogen storage system with a capacity of 1 liter and a pressure level of 8 bar, we can consider the following factors:

1. Tank Material Selection:

  Choose a material with high strength-to-weight ratio and good hydrogen compatibility. Common options include high-strength steel alloys, carbon fiber composites, or aluminum alloys. Consider the material's weight, cost, and safety characteristics.

2. Tank Geometry:

  Optimize the tank's geometry to maximize the storage capacity within the given volume of 1 liter. Consider cylindrical or spherical shapes as they offer efficient use of space and pressure containment.

3. Tank Wall Thickness:

  Determine the appropriate wall thickness to withstand the desired pressure level of 8 bar. The wall thickness will depend on the selected material and the tank's geometry. Perform stress analysis to ensure the tank's structural integrity.

4. Safety Features:

  Incorporate safety features like pressure relief valves, burst discs, and rupture disks to prevent over-pressurization and ensure the safe operation of the storage system. These features will release excess pressure in case of emergencies.

5. Insulation:

  Include effective insulation to minimize heat transfer and maintain hydrogen temperature. Insulation reduces energy losses and helps stabilize pressure within the tank.

6. Valve and Fittings:

  Select hydrogen-compatible valves and fittings capable of handling the desired pressure level. Ensure they provide efficient filling and emptying of hydrogen and allow for easy connection to other systems.

7. Materials Compatibility:

  Consider the compatibility of tank materials with hydrogen gas. Hydrogen can cause embrittlement in some materials, so it's crucial to choose materials that have been tested and proven to be compatible with hydrogen.

8. Weight and Portability:

  Optimize the design to minimize the overall weight of the storage system while maintaining safety and structural integrity. Consider the portability requirements if the system needs to be mobile.

9. Cost Considerations:

  Balance the cost of materials, manufacturing, and safety features while designing the system. Consider the trade-offs between different materials and manufacturing processes to achieve an optimal balance between cost and performance.

10. Regulatory Compliance:

   Ensure that the storage system design meets relevant safety standards and regulations for hydrogen storage. Consult local codes and guidelines to ensure compliance.

It's important to note that the design and optimization of a pressurized hydrogen storage system involve complex engineering considerations. Consulting with experts in hydrogen storage and working closely with experienced professionals in the field will help ensure a safe and efficient design.
