In order to study the influence of the flame- holder layout on the outlet temperature distribution,combustion efficiency and total pressure loss,the numerical simulation of combustion flow field for a ramjet combustor was completed.

The performance of the combustion flow field at the three conditions was analyzed for the gas turbine annular combustor.

The numerical simulation of combustion flow field for the plasma generator was performed by using eddy break up(EBU) combustion model,k-ε two-equation turbulent model and SIMPLEC algorithm.

A set of experimental studies were conducted to study complicated internal exhausted flow field generated by missile which was launched from a closed container-launcher.

Compared with other solid rocket engine, the nozzle of the solid rocket pulse has sharp curvature, which results in a complicated gas flow field, and without a heat-shield, which causes overheating in the structure of nozzle and nozzle pedestal.

The superposition between the helicopter rotor induced flow and the warship airwake leads to the formation of the complex wake,which affects the helicopter s control response and flight safety during take-off and landing from a warship.

The paper gives the measurements results of complex flow field about a delta wing coupled pitching and rolling oscillation at high amplitude in low speed wind tunnel .

To better the application of PTV technique in complex surface flow field,an automatic image segmentation method based on frame difference and adaptive threshold was established,and particle signature identification was introduced,which bettered the effect of particle recognition and tracking in complex flow field.
