| Research Abstract |
To resolve the environmental and energy issues, homogeneous charge compression ignition(HCCI) is expected to be one of the promising combustion technologies in terms of low emission and high efficiency. In this research project, Direct Numerical Simulation(DNS) code of turbulent combustion has been optimized for GPU-cloud supercomputer and the computational scheme which can be applied to practical combustors with a moving wall has been developed. DNS on autoignition and flame propagation of premixed mixture with inhomogeneity of fuel concentration and temperature has been conducted to reveal turbulent combustion mechanisms and flame-wall interaction in HCCI engines.
