Introduction
Perkenalkan saya Aisyah Rahmi Nurhanifah dengan NPM 2106707845, program studi Teknik Perkapalan tahun 2021.
Resume Pertemuan 1 (26/5/2023)
Pada pertemuan pertama, saya mempelajari bahwa metode nemuerik adalah metode yang digunakan untuk menyelesaikan suatu permasalahan matematika yang kompleks melalui pendekatan secara numerikal. Matematika adalah ilmu pasti, akan tetapi kemarin saya menyadari bahkan di matematika pun tidak semua jawaban absolut atau eksak (pasti). Contoh dari soal (x-1)^2/(x-1) dengan x = 1. Apabila langsung disubstitusikan maka hasilnya ada 0/0 atau tidak terdefinisikan, sedangkan apabila dijabarkan melalui pendekatan secara limit, maka hasilnya adalah 2. Akan tetapi 2 juga bukan merupakan jawaban eksak karena pendekatan secara limit menjadikan x mendekati 1, bukan x = 1 (absolut). Oleh karena itu, di dunia ini yang abosolut hanyalah Tuhan Yang Maha Esa. Pada pertemuan kemarin, saya juga mempelajari tentang “counciousness”. Dalam menyelesaikann suatu permasalahan, kita harus “councious” mengenai permasalahan tersebut dan mencari solusi untuk menyelesaikannya. Selain itu, kami juga mendapatkan tugas untuk mendesain 1 liter tabung hidrogen dengan tekanan 8 bar dan biaya maksimal Rp. 500.000,00
Design & Optimization of Pressurized Hydrogen Storage
To design and optimizing a Hydrogen Storage with specification: Volume: 1 Liter Pressure: 8 bar Budget: Rp.500.000,00 I use ChatGPT and here are the steps in designing and optimizing a Hydrogen Storage: Select Storage Method Choose the appropriate method for hydrogen storage based on your requirements. Common methods include compressed gas cylinders, cryogenic liquid storage, or solid-state hydrogen storage materials. Each method has its advantages and considerations in terms of cost, efficiency, and safety. Material Selection Select suitable materials for your chosen storage method. For compressed gas cylinders, consider materials such as steel or aluminum alloys with high tensile strength and compatibility with hydrogen. For cryogenic storage, choose materials with low-temperature resistance. For solid-state storage, explore materials with high hydrogen storage capacity. Design and Engineering Develop a design for the storage system, considering factors such as pressure vessels, insulation, valves, fittings, and safety mechanisms. Engage with engineers and experts in the field to ensure compliance with safety standards and optimize the design for performance and cost. Manufacturing Process Explore cost-effective manufacturing processes such as seamless cylinder fabrication or efficient welding techniques. Cost Optimization Consider cost optimization techniques to stay within your budget. Explore options such as optimizing the size and shape of the storage vessel, minimizing material usage while maintaining safety requirements, and considering cost-effective manufacturing processes. Simulation and Analysis Utilize numerical simulations and analysis tools to evaluate the performance and safety of the storage system design. Perform stress analysis, pressure simulations, and leakage assessments to ensure the system's integrity and reliability. Prototype and Testing Build a prototype based on the optimized design and conduct thorough testing to validate the performance and safety of the storage system. This step is crucial to identify any design flaws or operational issues before implementation. Compliance and Certification Ensure compliance with applicable regulations, standards, and certifications for hydrogen storage systems. Consult with relevant authorities and certification bodies to meet the required safety and performance criteria.
