    大型プラント内の熱交換器において、高温排熱気塊が風下側の各種装置に吸い込まれる事により装置の性能低下を引き起こすHot Air Recirculation(HAR)が問題になっている。人工物の影響を強く受ける地表付近の気象現象(微気象現象)がHAR発生において重要となると予想される。排熱源をモデル化した流れの数値計算によりHAR発生メカニズムを明らかにし、その予測に必要な気象情報の時空間スケールを同定する。微気象情報と実プラントでの観測結果の比較により、微気象情報に基づくHAR予測が可能であるかを検証する。さらに、微気象シミュレーションによるリアルタイムHAR予測システムのテストを行う。
    大型プラント内の列をなした熱交換器において、高温排熱気塊が風下側の熱交換器や各種装置に吸い込まれる事により装置の性能低下を引き起こすHot Air Recirculation(HAR)と呼ばれる現象が問題になっている。微気象情報を基にHAR現象を予測し各プラント運用を最適化することにより、HAR現象に起因するプラント運用効率の低下を防ぐことができると期待される。HAR発生メカニズムと支配パラメータを解明することを目的として、排熱源をモデル化した流れの直接数値計算(DNS)およびラージエディシミュレーション(LES)を実施した。まず、三次元排熱源構造物を通過する流れのDNSおよびLESの計算コードを構築した。本計算コードは有限差分法を用いたものであり、物体は埋込境界法により取り扱われる。計算コードはMPIにより並列化されており、スーパーコンピュータを用いた大規模数値計算が可能である。計算コードの検証のため、丘陵地形を過ぎる安定密度成層流れの数値計算を行った。丘陵上の乱流統計量が水槽実験結果とよく一致し、本計算コードが物体近傍の乱流現象の解析に有効であることを確認した。また、プラントにおける排熱を模擬した流れとして、噴流による熱拡散現象を対象とした数値計算を行った。流れ場から活発な熱拡散を引き起こす乱流領域を抽出し統計解析するデータ処理コードを構築した。数値計算結果を過去に行われた仮想プラント近傍の流れのシミュレーション結果と比較してHAR発生要因について考察した。次年度以降実施するプラントでの風況観測に向けた打合せを行い、観測に必要な機器を導入し準備を進めた。また、プラントの微気象予測に向けて、観測対象プラントを模擬した仮想プラントの電子データを作成した。
    計算コードの構築が完了し、プラントにおける排熱を模擬した流れの数値シミュレーションを開始することができた。構築したコードが建物などの物体周りの流れの数値計算へ適用可能であることが、丘陵地形を過ぎる安定密度成層流れの数値計算により確認された。また、流れ場から活発な熱拡散を引き起こす乱流領域を抽出し解析する手法についての論文がPhysics of Fluidsに掲載され、次年度以降実施する数値シミュレーションデータの解析準備が整った。また、プラントでの風況観測に向けた準備も順調に進んでいる。こうした本研究課題の取組・成果について「微気象制御学」領域シンポジウムや国内外の学会で発表した。
    本年度に構築した計算コードにより横風中に高温流体を噴出する流れのDNS(Direct Numerical Simulation)およびLES(Large Eddy Simulation)を実施する.計算条件を実プラントにおける過去の観測結果をもとに複数選定する。様々なパラメータに対する計算結果をプラント近傍の流れのシミュレーション結果や観測結果と比較し、HAR現象の発生条件を明らかにする。調和的予測班のMSSG微気象シミュレーション技術によるHAR現象の予測精度について検討する。また,DNSおよびLESによりHAR現象を引き起こす熱拡散の空間・時間スケールを求め、HAR現象の予測に必要な微気象情報の時空間スケールを同定することを目指す。これらの数値計算により予測されるHAR発生要因について検証するため、実プラントにおいて風況計測を行う。

    In recent years, the existence of nonequilibrium turbulence (or non-Kolmogorov turbulence) is unveiled, in which the energy flux and dissipation of turbulent kinetic energy are not balanced. However, it is not yet clear whether or not such kind of unsteady turbulence appears even at high or extremely low Reynolds numbers or high Mach number regime. In addition, it is not clear whether nonequilibrium phenomena are observed in various types of turbulent flows. The purpose of this study is to investigate in detail the turbulent energy generation and dissipation mechanism in various types of turbulent flows, including high Reynolds and extremely low Reynolds numbers and high Mach number regimes, and to clarify the nonequilibrium characteristics of such turbulent flows.

    Direct numerical simulations (DNS) and experiments of turbulent flows were conducted for investigating turbulent/non-turbulent interfacial (TNTI) layers. A stably stratified fluid can support propagation of internal gravity waves. The wave characteristics within the TNTI layer were revealed with DNS of stably stratified shear layers. In the DNS, long elongated flow structures and hairpin vortices were identified in the stably-stratified shear layers. Interaction between turbulence and shock wave was also studied with DNS and experiments, which confirmed that inhomogeneity of turbulence is one of the important factors of the interaction. Turbulent mixing near the TNTI layer was studied with DNS of turbulent jets and boundary layers, and a model for scalar dissipation rate is proposed for low-cost simulations of turbulent reacting flows. Two-color particle image velocimetry system was developed with pulse-operated laser diodes and a new algorithm for color contamination correction.

    Direct numerical simulations (DNS) were performed for stably stratified turbulence and compressible turbulence. Influences of internal gravity waves and pressure waves on turbulent/non-turbulent interfaces were investigated by detecting the turbulent fluid based on vorticity or potential vorticity. A multi-particle interaction model was proposed for molecular diffusion and thermal conduction. The performance of the model was evaluated with the DNS database of turbulent planar jets. The piston jet actuator with single/multiple orifice was experimentally studied with cylinder pressure measurement and flow visualization based on the shadowgraph method. These experiments revealed the relation between the cylinder pressure and jet Mach number.
