Dinamika Fluida Komputasi (CFD), Suhu Ekstrem, ANSYS Student 2025 R2Abstrak
Studi ini menganalisis efek suhu ekstrem pada kulit wahana antariksa selama masuk kembali ke atmosfer menggunakan metode Computational Fluid Dynamics (CFD) dan perangkat lunak ANSYS Student 2025 R2. Hasil analisis menunjukkan bahwa setiap material memiliki respons termal yang bervariasi. Paduan aluminium AL-7079 menunjukkan distribusi panas yang tidak merata, yang berpotensi menyebabkan tegangan termal dan retak6. Baja Karbon Cor rentan terhadap kelelahan material pada suhu ekstrem. Paduan magnesium AZ-31 tidak memiliki ketahanan yang memadai terhadap suhu ekstrem, menyerap panas yang berlebihan. Dari keempat material yang diuji, Titanium TI-55 menunjukkan kinerja termal yang paling unggul. Material ini mampu menyerap dan menghilangkan panas secara merata, mencegah titik panas, dan menjaga integritas struktural wahana dalam kondisi ekstrem. Studi ini menyimpulkan bahwa Titanium TI-55 adalah pilihan yang paling efektif untuk mengatasi tantangan termal dalam wahana antariksa.
