Torsional Strengthening of RC Beams with Continuous Spiral Near-Surface Mounted Steel Wire Rope
The strength of reinforced concrete members can be enhanced using externally bonded reinforcement (EBR) and near surface mounted (NSM) methods. However, small number of studies has adopted the NSM method for torsional strengthening. To date, no study has

Optimal Taylor-Couette flow: Radius ratio dependence [PDF]
Taylor-Couette flow with independently rotating inner (i) and outer (o) cylinders is explored numerically and experimentally to determine the effects of the radius ratio {\eta} on the system response. Numerical simulations reach Reynolds numbers of up to
