[期刊论文] 作者:Piotr Doerffer,Janusz Telega, 来源:黑龙江科技学院学报 年份:2013
为探究吕家坨井田地质构造格局,根据钻孔勘探资料,采用分形理论和趋势面分析方法,研究了井田7...
[期刊论文] 作者:Piotr DOERFFER,Slawomir DYKAS, 来源:Journal of Thermal Science 年份:2005
In this paper numerical calculations of the dry and humid air flows in the nozzle are presented. The dry air flow (adiabatic flow) and the humid air flow (flow...
[期刊论文] 作者:Piotr Doerffer,Oskar Szulc,, 来源:Journal of Thermal Science 年份:2007
Strong,normal shock wave,terminating a local supersonic area on an airfoil,not only limits aerodynamic per-formance but also becomes a source of a high-speed i...

[期刊论文] 作者:Piotr Doerffer,Oskar Szulc,Franco Magagnato, 来源:Journal of Thermal Science 年份:2003
The flow in transonic diffusers as well as in supersonic air intakes becomes often unsteady due to shock wave boundary layer interaction. The oscillations may...
[期刊论文] 作者:Piotr DOERFFER,Andrzej SZUMOWSKI,Shen YU, 来源:Journal of Thermal Science 年份:2000
During earlier research on shock wave/boundary layer interaction control, the effect of air humidity flow separation has been observed. This has inspired a more...
[期刊论文] 作者:Piotr DOERFFER,Oskar SZULC,Rainer BOHNING,, 来源:Journal of Thermal Science 年份:2006
Normal shock wave, terminating a local supersonic area on an airfoil, limits its performance and becomes a source of high speed impulsive noise. It is proposed...
[期刊论文] 作者:Minoru YAGA,Kenji YAMAMOTO,Piotr DOERFFER,Kenyu OYAKAWA,, 来源:Journal of Thermal Science 年份:2006
In this paper,some preliminary calculations and the experiments were performed to figure out the flow field,inwhich some rods were normally inserted into the m...
