RISCharacterization of Flow Structures in a Diesel Injector for Different Needle Lifts and a Fluctuating Injection Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims at analyzing the needle lift's influence on the internal flow of singlehole diesel injector to identify flow structures. A numerical ReynoldsAveraged Navier–Stokes (RANS) model of a singlehole diesel ...
Single Orifice Diesel Injector Flow Characterization and the Impact of Needle Lift Using Large Eddy Simulation and Proper Orthogonal Decomposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow in the injector's sac volume has been reported to influence diesel-injector nozzle flow, but few studies have characterized sac volume. Our study modeled flow in the sac volume using a large Eddy simulation (LES) ...
Explicit Algebraic Reynolds-Stress Modeling of Pressure-Induced Separating Flows in the Presence of Sidewalls
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reynolds-averaged Navier–Stokes (RANS) approach is used to simulate the steady-state of a family of pressure-induced turbulent separation bubbles in the presence of sidewalls. Different turbulence models are employed with ...
