| Abstract: | For PIV images capture,installation of a plane measuring side-window on the combustor wall is required,which has influence on the flow patterns in a micro-gas turbine combustor.It is therefore necessary to make correction for the data acquired from PIV experiments in order to approximate them to those for the original combustor without measuring side-window to the full extent.A new correcting method based on the CFD technique for PIV data correction was proposed,and the data from PIV experiments on the swirl combustor model were processed by the correcting method.The revised experimental results were compared with the data from numerical simulation,which found that the correcting method is beneficial to reducing the error of the flow patterns in the PIV images capture. |
