Drag Reduction Effect of Gradually-Varying Riblet Structures on Conical Rotating Disks
水下无人系统学报Based on the enclosed flow field conditions and optimized dynamic-static clearances, a gradually-varying riblet drag reduction structure was proposed by combining the drag reduction principle of uniform-sized riblets to address the problem of increased ...

Direct numerical simulation for investigation on yaw angle effects on riblets
Journal of Fluid Science and Technology, 2017 The yaw angle (φ) effect on riblets are investigated by parametrically conducted direct numerical simulation (DNS). Three configurations are adopted: standard straight riblet, sinusoidal riblet, and modified sinusoidal riblet. The height of the side wall

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport
Small Structures, Volume 7, Issue 2, February 2026.Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.Abstract We describe the Hettangian Caenogastropoda and Heterobranchia of the Luxembourg Sandstone Formation, a wedge of clastic sediments deposited along the eastern margin of Paris Basin during the Early Jurassic. Five new genera and 11 new species are erected: Bourguetia bipartita sp. nov., Globularia delsatei sp. nov., Oonia feidtorum sp.
