2021, Journal of Wind Engineering and Industrial AerodynamicsCitation Excerpt :Among these measures, the surface roughness measure shows considerable advantages. José (1991) (José, 1991a, 1991b) conducted a series of wind tunnel tests on circular cylinders with three types of surface roughness, i.e. the sandpaper, square mesh wire screen and spanwise ribs respectively. Based on the changes of mean and fluctuating aerodynamic forces and wind-induced pressures caused by the rough surfaces, it was revealed that the aerodynamic characteristics were improved through the effect of surface roughness on triggering the regime transition.
Reynolds number effects on the wind pressure distribution on spherical storage tanks
2021, Journal of Wind Engineering and Industrial AerodynamicsCitation Excerpt :Schewe (1983) tested the aerodynamic drag and lift coefficients in the Reynolds number range from 2 × 104 to 7 × 106, indicating that the drag coefficient was 0.52 in the trans-critical range when Re exceeded 3 × 106. Güven et al. (1980) and Duarte (1991a and 1991b) investigated the influence of surface roughness of cylinder on the aerodynamic coefficients, indicating a potential method to equivalently simulate the flow and load characteristics at high Reynolds numbers. Duarte (1992) and Zan (2008) investigated the aerodynamic loads on circular cylinders in turbulent flow, indicating that the transition of separation occurs at lower Re in turbulent oncoming flows.

2018, Marine StructuresCitation Excerpt :There have been numerous studies of the effect of surface roughness on the nearby flow around a circular cylinder and the VIV response of a circular cylinder [10–21]. As shown in Table 1, based on the boundary condition of the cylinder, the cylinders that have been studied can be divided into stationary cylinders [10–16], which are completely fixed, and oscillating cylinders [17–21], which are flexibly mounted. The studies of stationary cylinders are directed mainly toward the flow wake region, and include examinations of vortex shedding frequency, vortex shedding flow pattern and hydrodynamic forces induced by vortex shedding.
