This project aims to investigate the applicability of a theoretical model for vortex rings, developed by Kaplanski and Rudi (2005), to the analysis of vortex rings observed in direct injection gasoline engines. The investigators will also carry out a feasibility study on the further modification of this model, taking into account the effects of multiphase flow. They will also undertake further experimental investigation of vortex rings in these engines with particular emphasis on the essential parameter values required in order to develop the theoretical model. The project will examine the theoretical predictions of vortex ring properties against the values of typical parameters for gasoline engines which will allow a detailed comparison between the predictions of the model and experimental results to be made. Finally, the team will investigate the feasibility of developing a vortex ring model, capable of predicting the properties of vortex rings in gasoline engines.

本项目旨在研究Kaplanski和Rudi（2005）开发的涡环理论模型对分析直喷式汽油发动机中观察到的涡环的适用性。调查人员还将对进一步修改该模型进行可行性研究，考虑到多相流的影响。他们还将对这些发动机中的涡环进行进一步的实验研究，特别强调为了发展理论模型所需的基本参数值。该项目将根据汽油发动机的典型参数值，对涡环特性的理论预测进行检查，这将允许对模型预测和实验结果进行详细比较。最后，该团队将研究开发涡环模型的可行性，该模型能够预测汽油发动机中涡环的特性。
