The velocity vector fields resulted from high speed time-resolved particle image velocimetry (PIV) of the flow field inside an engine cylinder under steady-state conditions were investigated by proper orthogonal decomposition with the objective to compare the in-cylinder flow structures evolution and variation at different pressure differences 300, 450 and 600 mmH2O. The result demonstrated that mode 1 flow pattern was a good estimate of the ensemble-averaged tumble pattern. Moreover, there was a good correlation between mode 1 coefficients and the applied pressure difference. © 2018 Author(s). publisher: American Institute of Physics Inc. date: 2018 type: Conference or Workshop Item type: PeerReviewed identifier: El-Adawy, M. and Heikal, M.R. and Aziz, A.R.A. and Ismeal, M.A. and Wahhab, H.A.A.
