| 1 | Influence of Internal Channel Geometry of Gas Turbine Blade on Flow Structure and Heat Transfer显示文摘This paper presents the study of the influence of channel geometry on the flow structure and heat transfer, and also their correlations on all the walls of a radial cooling passage model of a gas turbine blade. The investigations focus on the heat transfer and aerodynamic measurements in the channel, which is an accurate representation of the configuration used in aeroengines. Correlations for the heat transfer coefficient and the pressure drop used in the design of internal cooling passages are often developed from simplified models. It is important to note that real engine passages do not have perfect rectangular cross sections, but include a corner fillets, ribs with fillet radii and a special orientation. Therefore, this work provides detailed fluid flow and heat transfer data for a model of radial cooling geometry which has very realistic features. | Ryszard Szwaba Piotr Kaczynski Janusz Telega Piotr Doerffer | 2017 | Journal of Thermal Science2017，26，6： | 4 |
| 2 | Flow Structure and Heat Exchange Analysis in Internal Cooling Channel of Gas Turbine Blade显示文摘This paper presents the study of the flow structure and heat transfer,and also their correlations on the four walls of a radial cooling passage model of a gas turbine blade.The investigations focus on heat transfer and aerodynamic measurements in the channel,which is an accurate representation of the configuration used in aeroengines.Correlations for the heat transfer coefficient and the pressure drop used in the design of radial cooling passages are often developed from simplified models.It is important to note that real engine passages do not have perfect rectangular cross sections,but include coiner fillet,ribs with fillet radii and special orientation.Therefore,this work provides detailed fluid flow and heat transfer data for a model of radial cooling geometry which possesses very realistic features. | Ryszard Szwaba Piotr Kaczynski Piotr Doerffer Janusz Telega | 2016 | Journal of Thermal Science2016，25，4： | 3 |
| 3 | Shock Wave Boundary Layer Interaction on Suction Side of Compressor Profile in Single Passage Test Section显示文摘The shock wave boundary layer interaction on the suction side of transonic compressor blade is one of the main objectives of TFAST project(Transition Location Effect on Shock Wave Boundary Layer Interaction).In order to investigate the flow structure on the suction side of a profile,a design of a generic test section in linear transonic wind tunnel was proposed.The experimental and numerical results for the flow structure investigations are shown for the flow conditions as the existing ones on the suction side of the compressor profile.Near the sidewalls the suction slots are applied for the corner flow structure control.It allows to control the Axial Velocity Density Ratio(AVDR),important parameter for compressor cascade investigations.Numerical results for Explicit Algebraic Reynolds Stress Model with transition modeling are compared with oil flow visualization,schlieren and Pressure Sensitive Paint.Boundary layer transition location is detected by Temperature Sensitive Paint. | Pawel Flaszynski Piotr Doerffer Ryszard Szwaba Piotr Kaczynski Michal Piotrowicz | 2015 | Journal of Thermal Science2015，24，6： | 3 |
| 4 | Correlates of subjectively and objectively measured physical activity in young adolescents显示文摘背景:很多研究利用自我报告评价青少年个体活动水平,而不是通过客观测量。利用自我报告方式得到的结果与客观测量体力活动相比,可能产生并不存在的关联。本研究旨在探讨与体力活动相关的假设在主客观测量体力活动间的联系。方法:通过加速度计测量对被试青少年(共232人,其中男性101名,平均年龄12.3岁)进行至少4天体力活动检测,同时完成调查评估,包括中高强度体力活动(MVPA)、运动能力、参与度、享受度和自我效能感,并测量身高、体重和BMI。结果:用分层回归模型通过控制性别、种族和BMI的Z值,发现性别、BMI的Z值与客观测量得到的MVPA明显相关:同时,仅性别与客观测量的体力活动总量明显相关。相反,用单一模型衡量主观MVPA关系时发现,仅体力活动的享受度、自我效能感与自我报告的体力活动明显相关。结论:通过自我报告和使用加速度计的客观监测方法测量青少年MVPA,两者所得结果存在较大差异。今后研究若要确定与青少年MVPA相关的因素,应谨慎选择测量方式。 | Kelly Kavanaugh Justin B.
