Description
を含むことができる。孔は、非均一な熱伝達を可能にするための所望の選択的インピンジメントパターンに対応する所定の非均一分布で配列されている。様々な任意選択の項目及び修正が可能である。
を含む。上述のように、様々な任意選択の項目及び修正が可能である。
従って、定常状態に達するまでのワインドアップ中、達成される選択的熱制御は、実質的に孔144に対向するケーシング121のインピンジ領域の加熱となる。ワインドアップ中又は定常状態に達した時点では、抽出された圧縮機ガスがインピンジ領域を冷却する機能を果たすことになる。従って、プレート140は、選択的熱制御装置とみなされ、内側ケーシング121のインピンジ領域を加熱又は冷却するために配管ではなくインピンジメントによって少なくとも実質的に作動することができる。
