Frost formation on the heat exchangers of the air conditioning equipment causes the serious energy loss, thus the anti-frost formation technique is the urgent task. The purpose of this study is to clarify the frost growth process by estimating the relationship between the frost-crystal micro structure and the heat-mass transport phenomena in the frost layer. The three-dimensional microstructure of the frost crystal was measured using X-ray micro CT, and the effect of the cooling surface properties on the crystal structure was evaluated. Furthermore, the combined heat conduction of ice crystals and moist air in the frost layer was analyzed using the measured three-dimensional microstructure data. The surface temperature of the frost layer rises as the frost layer grows, while the temperature of the bottom of the frost layer decreases. As a result, ice crystals at the bottom of the frost layer grow by the water vapor supplied from the sublimation in the frost layer.

The experiments were conducted using two types (circular hole and shaped film cooling hole geometries ) of scaled-up model of film cooling holes installed at the bottom surface of a low-speed wind tunnel in order to measure detailed examination of mixing flow features of film cooling air with mainstream. Instantaneous and simultaneous 3-D flow field was measured by LIF and PIV, and time-averaged film cooling effectiveness was measured by PSP. Furthermore, numerical analysis based on Large Eddy Simulation developed by one of the applicant was conducted and the accuracy of numerical analysis is improved by comparison with measured data.
The 3-D mixing flow field data and film cooling effectiveness data together with film cooling hole geometries and main flow conditions measured in the wind tunnel were prepared as an open data in web site for the purpose of utilizing as a database for the verification of numerical analysis of film cooling, -
Development of Flame Temperature and Velocity Measurement Using Rayleigh Scattering Extinction Ratio

The spatial profile of Rayleigh scattering depends on the laser polarization angle and we change the angle of a short harmonic generator inside the laser for leaning the polarization angle. The scattering intensity from the leaned laser light plane was measured using two CCD cameras with image-intensifiers. And one camera measures both of Rayleigh scattering and Mie scattering and the other one detects only the background light. We develop to modify the laser intensity profile which depends on the angle of the short harmonic generator. We apply this method to temperature measurement in a lean premixed flame and make it possible to measure the temperature profile without the influence of the background light intensity.

Development of Multi-Scale Large Eddy Simulation Based on Velocity Reconstruction by Vortex Elements on the Domain Interfaces

In this study, a numerical simulation method for predicting complex turbulent heat transfer fields was developed based on a LES (Large Eddy Simulation) method. Contrary to my initial expectations, the development of a velocity reconstruction method, which is based on vortex elements near the domain interfaces, was not accomplished perfectly. Instead, a multi-block LES method was newly developed based on three-dimensional interpolation techniques. By applying this method, a new concept of turbulent flow simulation, “concurrent simulation” was proposed and developed. The concurrent simulation technique was applied to investigate the effect of a slight change in the shape of turbulence promoters on the resultant turbulent heat transfer fields downstream the turbulators under the completely same fluctuating inflow fields for each turbulator.

In this study, we developed simultaneous visualizing techniques of lean premixed flame and flow fields in a cylinder glass by high-speed PIV measurement. We present characteristics of flame propagation in a premixed burner with swirling flow in order to investigate unsteady flame behavior in the premixer. Two kinds of mixture gas supply techniques were used in order to investigate the characteristics of flame propagation. In the premixer of the closed center swirler with swirling flow, the tip of the flame was highly stretched and received flame extinction and the flame propagation further upward was prevented. In the premixer of the open center swirler, it was confirmed that flame was pressed back to downstream of the premixer by the axial high velocity region generated by impingement flow from center hole of the swirler.

Fundamental study on the innovative film cooling technologies to suppress the mixing process with adding swirling motion to the coolant

This study has been conducted to investigate a new film cooling method that utilizes swirling coolant flow through circular and shaped film cooling holes. The mixing phenomena with a film cooling air and a mainstream was measured by a instantaneous and simultaneous LIF and PIV methods, and the film cooling effectiveness on the wall was measured by PSP.
It appeared from the results that, in the case of a circular film-cooling hole, the penetration of the coolant jet into the mainstream was suppressed by the strong swirling motion of the coolant and attained 100% heigher film cooling effectiveness. As a result, the film cooling effectiveness on the wall maintained a higher value behind the cooling hole over a long range. Additionally, the kidney vortex structure disappeared. For the shaped film cooling hole, the coolant jet spreads wider in the span-wise direction. Thus, the pitch-averaged film cooling effectiveness downstream was 50% higher than that in the non-swirling case. -

In this study, we present an instantaneous and simultaneous measurement of 2-D mixing behavior and temperature distributions by combining acetone LIF and Rayleigh scattering. We examined air-fuel mixing characteristics in an unburned region where is adjacent to a reaction zone by laser induced fluorescence. Acetone vapor, which fluoresces by UV laser light, was used as a tracer. The CH_4 concentration was estimated from the acetone concentration, which was obtained by acetone LIF intensity. The mixing behavior has been evaluated by measuring CH_4 concentration distributions. It was clarified the suitability of the measurement technique based on the simultaneous measurement and simulation results in a laminar premixed flame. Relationship between inhomogeneous fuel distributions and flame base stability was clarified by simultaneous measurement results in lean premixed flame.

Grant amount：\3640000 （ Direct Cost: \2800000 、 Indirect Cost：\840000 ）
In this study, fast and precise simulation techniques to simulate complex heat and fluid flows in wind tunnel tests were developed to obtain detailed information from wind tunnel experiments. For example, time-series of inflow velocity fluctuation measured in wind tunnel tests were modeled with random Fourier modes and applied to the simulations to reproduce the realistic turbulent inflow. The effectiveness of the method was confirmed by the comparison between experiments and simulations of the starting process in a shock tunnel and by the prediction of complex flow and heat transfer fields at the leading edge of a symmetric airfoil in a low speed wind tunnel.

H19年度では,種々のフィルム冷却孔形状が主流と冷却空気の混合メカニズムに与える影響をより詳細に検討するため,前年度に開発したアセトンを用いたLIFによる濃度場(熱・物質輸送のアナロジーにより温度場に相当)の時間平均分布測定法を,瞬時値の計測が可能になるように改良を行った.また,流れ場の計測にPIVを用いることで,測定断面における流れ場と濃度場(温度場)の瞬間同時測定を可能にした.これにより,主流と冷却空気の混合状態の詳細を捉えることが可能になり,種々の冷却孔形状がフィルム冷却の熱流動構造にもたらす効果を瞬間流れ場・温度場の観点から検討することが可能になった.具体的には円孔とシェイプト孔による混合状態の相違を瞬時場に基づいて検討した結果,円孔とシェイプト孔の双方で,主流と冷却空気の速度差に由来する自由せん断層の不安定性に起因する準周期的な渦によって,主流と冷却空気め混合が促進されていることが明らかになった.また,円孔では冷却空気が主流を貫通し,さらに冷却孔出口近傍で形成される腎臓形状の二次渦による冷却空気の巻き上げによって,冷却孔下流での冷却効果が減少することが分かった.また,数値計算においては,LESに比して計算負荷が低く,工学的な応用にも適用可能なDESを用いて種々の冷却孔形状に関する非定常乱流数値解析を行い,実験との比較を行った.その結果,時間平均場におけるフィルム冷却効率分布の形状や大きさを比較的良い精度で再現できるものの,瞬時流れ場・温度場の再現性には問題が残ることが分かった.また,シェイプト孔においては冷却空気の主流への拡散がDESでは低くなる傾向が見られた.以上の結果から,フィルム冷却の熱流動場を最適化する上での冷却孔形状の変更指針を得るとともに,その効果を評価する実験手法,数値解析手法の構築を行うことができた.
