Abstract: Abstract Wall roughness is often found to have evident influences on flow-related processes in rock fractures. In this work, we first define the primary wall roughness to have dominating effects on the overall flow, whereas… read more here.

DOI: 10.1063/5.0276339
Abstract: The multi-scale characteristics of wall roughness are the main factors inducing particle deposition in pneumatic conveying bend pipes. However, existing simplified models cannot effectively characterize the complex features of rough walls. To elucidate the mechanism… read more here.
