Free Flight of a Two-Dimensional Circular Projectile in a Quiescent Fluid
碩士 === 國立清華大學 === 動力機械工程學系 === 106 === We do the research of the free flight of a two dimensional circular projectile in a quiescent fluid. Calculate the pressure drag and form drag of the projectile, and use the drag with Newton’s second law to find the real projection trajectory of projectile in q...

Calculate the pressure drag and form drag of the projectile, and use the drag with Newton’s second law to find the real projection trajectory of projectile in quiescent fluid. We also investigate how the initial speed, the initial rotation speed, and the density of projectile influences the projection trajectory. We use the implicit virtual boundary method with non-staggered Cartesian grid system and patch grid to calculate and reduce the calculating time. Lee, Shong-Leih 李雄略 2018 學位論文 ; thesis 47 zh-TW |
