中文简介:
本课程首先向学生介绍与颗粒沉积物质的运输和沉积相关的流体动力学方面。重点是湍流剪切流的结构和流体运动对松散沉积物床的作用力。以流体动力学为背景,该课程将沉积物运动作为床荷载和悬浮荷载,以及波纹和沙丘床形式的几何,运动学和动力学。本课程以当前生成的主要沉积结构的基本材料结束,重点是交叉分层。
课程简介: This course begins by introducing students to aspects of fluid dynamics relevant to transport and deposition of particulate sedimentary materials. Emphasis is on the structure of turbulent shear flows and the forces exerted by fluid motions on bed of loosed sediment. With fluid dynamics as background, the course deals with sediment movement as bed load and suspended load, and with the geometry, kinematics, and dynamics of ripple and dune bed forms. The course concludes with basic material on the styles of current-generated primary sedimentary structures, with emphasis on cross stratification.
关 键 词: 流体运动; 沉积物输送; 湍流边界层; 应力; 振荡流,; 平面层压
