Kavitasi

Kerusakan oleh gelembung kavitasi yang tampak pada baling-baling suatu kapal.

Dalam mekanika fluida dan teknik, kavitasi umumnya merujuk kepada fenomena yang mana tekanan statis suatu cairan berkurang hingga lebih rendah daripada tekanan uap cairan tersebut, menyebabkan terbentuknya ruang kecil berisi uap di dalam cairan tersebut.[1] Saat terkena tekanan yang lebih tinggi, ruang berisi uap ini, yang biasa dikenal sebagai "ruang hampa" atau "gelembung", runtuh dan menghasilkan gelombang kejut kuat yang dapat merusak mesin.
