RISNumerical Prediction of Impact Force in Cavitating Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical method including a macroscopic cavitation model based on the homogeneous flow theory and a microscopic cavitation model based on the bubble dynamics is proposed for the prediction ...
Numerical Analysis of Unsteady Viscous Flow Through a Weis-Fogh-Type Ship Propulsion Mechanism Using the Advanced Vortex Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The velocity and pressure field of a ship’s Weis-Fogh-type propulsion mechanism are studied in this paper using an advanced vortex method. The wing (NACA0010 airfoil) and channel are approximated ...
Numerical Simulation of Vortex Shedding and Lock-in Characteristics for a Thin Cambered Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, vortex-shedding patterns and lock-in characteristics that vortex-shedding frequency synchronizes with the natural frequency of a thin cambered blade were numerically investigated. The ...
A Thermohydrodynamic Analysis of Dry Gas Seals for High Temperature Gas Cooled Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comprehensive analysis method is proposed to resolve the problem of simulating the complex thermoflow with two kinds of distinct characteristic lengths in a dry gas seal. A conjugated simulation of the complicated heat ...
Influence of Measurement Variability of International Roughness Index on Uncertainty of Network-Level Pavement Evaluation
Publisher: American Society of Civil Engineers
Abstract: International roughness index (IRI) is widely employed for evaluating pavement performance. It is a critical indicator used by state transportation agencies to identify the maintenance demands for road sections. However, ...
