Evaluation of surface roughness and bond-slip behavior of new textured epoxy-coated reinforcing bars
… epoxy-coated (TEC) reinforcing bars with applied roughness to improve the bond between concrete and steel while providing corrosion protection. This study investigates the surface roughness of different types of TEC bars and how it impacts the bar’s bond-slip behavior with concrete, both …

Structure of 2-D and 3-D Turbulent Boundary Layers with Sparsely Distributed Roughness Elements
… than 7000. Very uniform circular cylindrical roughness elements of 0.38mm, 0.76mm and 1.52mm height (k) were used in square and diagonal patterns, yielding six different roughness geometries of rough-wall surface. For the 2-D rough-wall flows, the roughness Reynolds numbers, based on the …
