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). date: 2018 publisher: American Institute of Physics Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85057309285&doi=10.1063%2f1.5075568&partnerID=40&md5=b9d617060eda8b1dab9fefc85584667a id_number: 10.1063/1.5075568 full_text_status: none publication: AIP Conference Proceedings volume: 2035 refereed: TRUE isbn: 9780735417618 issn: 0094243X citation: El-Adawy, M. and Heikal, M.R. and Aziz, A.R.A. and Ismeal, M.A. and Wahhab, H.A.A.
