Implications for flow resistance and sediment transport Michael P. Lamb* , Fanny Brun and Brian M. Fuller Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, CA, 91125 *[email protected] Key Points: 1. Direct measurements of lift and drag forces were made on cobbles in steep flume experiments with shallow, rough flow over a planar bed 2. As flows shall...
Meso-scale structure existing in the form of particle clusters or strands in concurrent-up gas–solid two-phase flow has been extensively corroborated in experimental research. However, its significant effects on interfacial drag coefficient are seldom taken into account in current computational fluid dynamic (CFD) simulations by using the two-fluid models. The energy-minimization multi-scale (E...
When the body is running at fully immersed condition in viscous fluid, there are two components of resistance, i.e. frictional resistance and form drag. When it is near the free surface, the additional drag encountered to the body which is wave-making drag. This paper is presents the hydrodynamic performance of high-speed Unmanned Underwater Vehicle (UUV) in fully immersed condition. We did 100...
