中文摘要 | 本研究之目的在於應用微機電製程技術開發一全新之微薄膜冷卻晶片,此實驗晶片模型內含有陣列式微溫度感測器以及微加熱器,其中微陣列式溫度感測器由入口區起將微溫度感測器以由密至疏排列共五十組、微加熱器一組以及提供氣體出口之微噴口,而微感測器具有高精確度,微加熱器部份具有可提供均勻高熱通量之加熱功能,此外藉由特殊之材料選擇,使得微噴口處除了具有良好之絕熱性以外,另可輕易變化各種不同高度,使得實驗模型可輕易改變其實驗條件。如此一來將可對於微薄膜冷卻之物理現象進行釐清。 |
英文摘要 | The object of our study will focus on the fabrication development for the micro film-cooled thermal chip. This thermal chip will have 50 temperature sensors, with high accuracy, starting from the exit of the slot nozzle to measure the film cooling effectiveness. In order to provide better thermal insulation, low thermal conductivity materials were selected to fabricate the slot and the film-cooled wall. Therefore, the heater on the wall can provide a perfect uniform heating condition. The height of slot can be varied at different depths. This can be used to study film cooling performance of micro wall jet at different thickness. To our knowledge, this kind of micro film-cooling performance study has not been found in the literature. The results will have a very significant impact on the gas turbine cooling design. |
