Large-scale intake generated flow structures, such as swirl and tumble, are known to have a significant effect on the combustion behaviour and have been widely studied by the automotive research community. Traditionally, the standard tools available to assess the in-cylinder flow behaviour inside an engine are either steady-state flow rigs or research engines with optical access. Steady-state flow rigs are used to evaluate the bulk motion using some integral parameters. Whilst the optical measurements are used to investigate detailed in-cylinder flow conditions. To assess the recent developments, principles and applications of stereoscopic particle image velocimetry to engine flow measurements are presented and discussed. © 2021 THE AUTHORS Y1 - 2021/// VL - 60 UR - https://www.scopus.com/inward/record.uri?eid=2-s2.0-85100673539&doi=10.1016%2fj.aej.2021.01.060&partnerID=40&md5=d158f86f53665ec45f52ff6774b7ba23 JF - Alexandria Engineering Journal A1 - El-Adawy, M.
