RISTransient Simulation of the Aerodynamic Response of a Double-Deck Bus in Gusty Winds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of the research reported in this paper was to investigate the aerodynamic response of a double-deck bus in gusty winds using a detached-eddy simulation (DES). The bus was subjected ...
LES Study of the Influence of a Train-Nose Shape on the Flow Structures Under Cross-Wind Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cross-wind flows around two simplified high-speed trains with different nose shapes are studied using large-eddy simulation (LES) with the standard Smagorinsky model. The Reynolds number is ...
Numerical Study of the Flow Around a Bus-Shaped Body
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow around a simplified bus is analyzed using large-eddy simulation. At the Reynolds number of 0.21×106, based on the model height and the incoming velocity, the flow produces features ...
Flow Around a Simplified Car, Part 1: Large Eddy Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large eddy simulations (LES) were made of flows around a generic ground vehicle with sharp edges at the rear end (an Ahmed body with a 25° angle of the rear slanted surface). Separation ...
Flow Around a Simplified Car, Part 2: Understanding the Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Results of a large eddy simulation (LES) are used to explore the flow around a generic car model. A new, refined picture of this flow is established. Many parts and aspects of this flow ...
Large Eddy Simulation Investigation of the Hysteresis Effects in the Flow Around an Oscillating Ground Vehicle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents large eddy simulations (LES) of flow around a simplified vehicle model oscillating around its vertical axis. The frequency of the Strouhal number St = 0.068 and a relatively ...
Comparison of Partially Averaged Navier–Stokes and Large-Eddy Simulations of the Flow Around a Cuboid Influenced by Crosswind
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Th e paper presents a partially averaged Navier–Stokes (PANS) simulation of the flow around a cuboid influenced by crosswind. The results of the PANS prediction are validated against experimental ...
