Comparison of transport methodologies on near-field pollutant dispersion in urban environments using CFD by Tee, Clarence Wei Tat

“…The focus of this study is to understand and quantify the differences between the two models when applied to near-field dispersion of heavy gases. The two methodologies are validated by simulating the dispersion phenomena for two test cases which largely bear resemblance to urban settings: a three-dimensional street canyon setup and the Mock Urban Setting Test (MUST) field experiment. …”

Dynamic behavior of reinforced concrete beams under varying rates of concentrated loading by Adhikary, Satadru Das, Li, Bing, Fujikake, Kazunori

“…LS-DYNA, an explicit finite element program widely used for three-dimensional nonlinear transient analysis of structures, was employed in this study to provide numerical simulations of RC beams under varying loading rates. Three-dimensional finite element (FE) models of RC beams have been described and verified with the experimental results, followed by a parametric study to investigate the influence of the longitudinal reinforcement ratio, the transverse reinforcement ratio and the shear span to effective depth ratio. …”
