On the gas loss from ventilated supercavities
Web2010). A supercavity can be formed at low speeds by ventilating non-condensable gas into the low-pressure region around a cavitating object (i.e., cavitator), termed as artificial or ventilated supercavitation (Kawakami and Arndt 2011). Ventilated supercavitation is generally characterized Web26 de mar. de 2024 · But gas can also be a symptom of certain health conditions, including: 1. Gastrointestinal (GI) disorders, like irritable bowel syndrome (IBS) and chronic …
