Numerical Simulation of Swirling Port-Valve-Cylinder Flow in Diesel Engines

Investigation On Flow Field In Simplified Piston Bowls for Di Diesel Engine

“…Mao, Buffat and Jeandel (1994) calculated the intake and compression strokes for an axi-symmetric case using a finite element method but did not present any validation. Aita et al (1991) studied the swirl motion in the cylinder during the intake and compression strokes on a real geometry with one intake valve, but presented little validation of their calculations. Chen, Veshagh and Wallace (1998) performed calculations of the full intake and compression processes and presented some comparisons with experimental data.…”

Numerical investigation of piston bowl geometry and swirl ratio on emission from diesel engines

“…McCracken et al [15] performed combustion simulation to gain insight into the swirl-spray interactions in a diesel engine. Aita et al [16] conducted a study to understand the flow behavior through an intake port-valve assembly during the intake and compression stroke and observed a strong interaction between swirling motion and shape and position of piston bowl. Gan et al [17] conducted a detailed review on various parameters such as initial swirl ratio, nozzle configuration affecting the performance and emission characteristics of diesel engine.…”

Flow Field Simulation in Water Washing Tank of Explosion-Proof Diesel

“…It is also impossible to obtain the flow image even open an observation mouth on the tank-walls, because the observation mouth will soon be contaminated after the starting of diesel engine. Therefore, through the ANSYS CFX/Fluent module, the simulation of gas flowing in the exhaust water washing tank of EPD was conducted [2][3][4][5][6][7][8][9]. It is the only means to grasp the gas-liquid flowing condition inside the water-washing tank, and it will provide a reference for the future optimized design of water-washing tanks.…”
