| Research Abstract |
In order to develop the effective control method for a heat and mass transfer and a mixing in engineering applications, we investigate the compound jet which is assembled with a number of jets. Both a mixing-state evaluation technique using statistical entropy and an extraction technique of large-scale flow structures using POD (proper orthogonal decomposition) method are investigated and are found to be useful in the evaluation of the performance of compound jets. A vector control of nozzle and the control method for compound jets are proposed and applied to the mixing enhancement of both free jets and impinging jets. As a result it is found that the proposed methods lead to the improvement of the mixing performance.
