A New Estimation Method of Turbulent Flow Structures Effective for Impingement Heat Transfer Augmentation
スポンサーリンク
概要
- 論文の詳細を見る
The primary purpose of this work is to construct a new method how to define the turbulent flow structures effective for heat transfer augmentation. The flow field consists of a submerged liquid jet issuing from a convergent slot nozzle and a circular cylinder for heat transfer placed perpendicular to and on the jet centerline. Two small cylinders were inserted into the jet stream to examine the effectiveness of heat transfer augmentation. Time-series data of the jet centerline velocities were analyzed by a wavelet transformation. The information entropy and expectation can successfully extract the intermittent turbulent structures effective for the impingement heat transfer augmentation from the developing jet structures.
