Abstract: Hydroelectric power resources constitute a renewable and economic means of providing electricity to serve the energy needs of our modern society. As dams get older, there is a need to ensure that their conditions of safety ...

Abstract: A numerical study has been performed of the air/fuel preparation process in a cold-starting port-injected spark-ignition engine. The latest models were implemented for spray impingement and ...

Abstract: In this paper, the Lagrangian finite element method is formulated along with the Bingham model for simulating natural transient slurry flows. The numerical model thus developed is validated with available experimental ...

Abstract: A multicomponent droplet vaporization model including both gas and liquid phase transport processes was developed for multidimensional spray computations. This paper focuses on two effects altering ...

Abstract: Integral constitutive equations of the endochronic type with only two easily determined material constants are shown to predict with computational ease the stress (plastic strain) response of ...

Abstract: Slope failures in fill slopes formed by loosely compacted, completely decomposed granite in Hong Kong occur commonly during intense tropical rainstorms. The stress path greatly influences the shear strength of the soil ...

Abstract: The traditional approach for assessing the stability of slopes is using limit equilibrium methods. Recently, many efforts have been made to utilize limit analysis methods based on the upper bound and lower bound limit ...

Abstract: Soil nailing is commonly used for stabilizing cut slopes and retaining structures. The technique is, however, seldom used in stabilizing old loose fill slopes that were not constructed to the current standards. There is a ...

Abstract: Results of field monitoring of moisture content and matric suction at the crest and berm of a large cut slope in completely decomposed granite in Hong Kong are reported. Field moisture content and matric suction clearly ...

Abstract: A laboratory study was conducted to investigate the behavior of soil nails embedded in loosely compacted sandy fills. By varying the overburden pressure, the peak pullout force and the load–displacement behavior were ...
