RISImpact of Stratification Mechanisms on Turbulent Characteristics of Stable Open-Channel Flows
Publisher: American Meteorological Society
A 3D Compressible Flow Model for Weak Rotating Waves in Vaneless Diffusers—Part I: The Model and Mach Number Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional compressible flow model is presented to study the occurrence of weak rotating waves in vaneless diffusers of centrifugal compressors. The diffuser considered has two parallel ...
A 3D Compressible Flow Model for Weak Rotating Waves in Vaneless Diffusers—Part II: Detailed Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 3D compressible flow model was presented in Part I of the paper to study the occurrence of weak rotating waves in vaneless diffusers of centrifugal compressors. In this paper, detailed ...
Probabilistic Assessment for Slope Using the Generalized Chebyshev Inequalities
Publisher: ASCE
Abstract: This paper aims to estimate the probability of failure (Pf) of slope based on Chebyshev inequalities. Traditionally, for a slope reliability analysis, the supposed distribution types of shear strength parameters are employed; ...
Active Stability Analysis of 3D Shallow Tunnel Face with Longitudinally Inclined Ground Surface Based on Nonlinear Mohr–Coulomb Failure Criterion
Publisher: ASCE
Abstract: The longitudinally inclined (the tunnel excavation direction) ground surface often appearing at the shallow tunnel entrance and exit zone threatens and reduces the tunnel face stability. However, studies on this stability ...
Reliability Assessment of Tunnel Based on P-Wave Seismic Velocity
Publisher: American Society of Civil Engineers
Abstract: This paper aims to propose a new method to analyze the stability of a tunnel using P-wave seismic velocity (Vp) with the help of the Tunnel Seismic Prediction 23 plus system (TSP23PLUS). On one hand, the relationship between ...
Upper-Bound Limit Analysis of Rock Slope Stability with Tensile Strength Cutoff Based on the Optimization Strategy of Dividing the Tension Zone and Shear Zone
Publisher: ASCE
Abstract: The contribution of tensile cracks to the stability of cracked slopes is important. The tensile characteristics of tensile cracks have a significant influence on the stability of rock slopes. Therefore, in this paper, based ...
An Improved Creep-Fatigue Life Model Involving the Cyclic Softening/Hardening and Stress Relaxation Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, improved creep-fatigue life prediction models based on time fraction (TF) and ductility exhaustion (DE) rule are established for creep-fatigue life prediction of components at elevated temperatures. Cyclic ...
