RISAnalysis of In Cylinder Turbulent Flows in a DISI Gasoline Engine With a Proper Orthogonal Decomposition Quadruple Decomposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The proper orthogonal decomposition (POD) method is applied to analyze the particle image velocimetry (PIV) measurement data and large eddy simulation (LES) result from an incylinder turbulence flow field in a fourvalve ...
Computer Simulation of Combustion Process in a Piston Engine With a Porous Medium Regenerator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the regenerative engine, effective heat exchange and recurrence between gas and solid can be achieved by the reciprocating movement of a porous medium regenerator in the cylinder, which considerably promotes the fuelair ...
Investigation of In-Cylinder Engine Flow Quadruple Decomposition Dynamical Behavior Using Proper Orthogonal Decomposition and Dynamic Mode Decomposition Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to study the in-cylinder flow characteristics, one hundred consecutive cycles of velocity flow fields were investigated numerically by large eddy simulation, and the proper orthogonal decomposition (POD) algorithm ...
