08:18, 29 January 2026 SanzSkuy talk contribs created page CFD: what is it and why (Created page with "Dulu, setiap kali manusia mau bikin pesawat, '''eksperimen itu wajib hukumnya'''. Sebelum pesawat beneran terbang di dunia nyata, desainnya harus diuji dulu pakai alat khusus yang namanya '''wind tunnel'''. Di situ, model pesawat dialiri udara buatan supaya insinyur bisa melihat bagaimana aliran udara, tekanan, gaya angkat, dan hambatan bekerja. Selama puluhan bahkan ratusan tahun, '''wind tunnel''' jadi senjata utama dalam pengembangan pesawat. File:Wind-tunnel.jpg|t...")
