An extraction of cycle-to-cycle variation of in-cylinder flow using temporal / spatial averaging and a proposal of variable sized spatial filtering

Nihon Kikai Gakkai ronbunshu, 2019
Cycle-to-cycle variation (CCV) of in-cylinder flow occurs in internal combustion engines. It is necessary to analyze CCV of flow to separate averaged-flow (as low frequency / low wave number) from turbulence (as high frequency / high wave number ...
