| Abstract: | The author compared the measurements of flow field in shallow ω-shaped, deep ω-shaped and plum blossom-shaped combustion chambers using the LDV. The results showed there are quite differ- ences among the flow fields of these three chambers. The ω-shaped chamber had the highest tangential speed,the plum blossom-shaped chamber had the biggest turbulent intensity while the tangential speed and turbulent intensity of the shallow ω-shaped chamber were smallest ones. |

| Keywords: | combustion chamber tangential speed turbulent intensity measurement flow field. |
