| Abstract: | Different data logging and processing methods for turbulent flow field measurement inside the cylinder and combustion chamber of internal combustion engine were tested and discussed in this paper. Comparisons are made for the influences of different statistical average methods, sampling frequencies and the widths of time-window etc. on the results of turbulence parameters obtained by CTA. Also comparison is made between the results obtained by all-orientational and 3 dimensional measurements. |
