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 ...

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 ...

Abstract: The design of the intake port plays a critical role in the development of modern internal combustion (IC) engines. The traditional method of the intake port design is a timeconsuming process including a huge amount of tests ...

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 ...

Abstract: Injection flow dynamics plays a significant role in fuel spray; this process controls the fuel–air mixing, which in turn is critical for the combustion and emissions process in diesel engine. In the current study, an ...

Abstract: Particle image velocimetry (PIV) system was used to measure the tumble structure of the incylinder airflow in a fourvalve optical gasoline direct injection (GDI) engine. The tumble ratio was controlled by a flap in the ...

Abstract: The turbulent boundary layer flow in internal combustion (IC) engines has a significant effect on the in-cylinder flow and the wall heat transfer. A detailed analysis of the in-cylinder near-wall flow was carried out on ...

Abstract: The utilization of floating breakwaters (FBs) represents a significant contribution to the field of offshore protection. In this paper, the interactions of the convex-type FB with water waves are numerically investigated. ...
