WebMar 15, 2024 · One of the challenges, especially at low speeds, is the behavior of flow at high angles of attack, which usually leads to asymmetric separation of flows around slender bodies and increased side force. In this paper, a cylindrical cone is examined numerically. For this study, an asymmetric grid is used to capture this expected phenomenon. … Web1 hour ago · Florida retiree says lesbian squatters with '15' pit bulls trashed rental property she owns to tune of $38,000 after lying to cops they'd paid deposit and showing fake receipt
