... is encouraging too. In addition, radiation is simulated in the FEA model based on the usual gray body assumptions and Lambert's law for the coupled computation. It has been shown that at the high power (HP) condition, the radiation for the inner cylinder is approximately 11% of its convective heat flux...

...Jian Liu; Honghu Ji Investigations on infrared (IR) radiation suppression of axisymmetric vectoring exhaust nozzle (AVEN) are meaningful, due to the requests for maneuverability and IR stealth capability of aircrafts. In this paper, the synthetic suppression scheme of film cooling and low...

... is employed to accurately account for the radiation effects. Optically thin (OT) and PMC–gray models are also employed to show the differences between the simplest radiative calculation models and the most accurate radiative calculation model, i.e., PMC–LBL, for the gas turbine burner. It was found...

... Combustors Composites Cooling Experimental Gas turbine technology Heat transfer Modeling Radiation Stress analysis Temperature Thermal With the goal of improving the fuel efficiency and environmental friendliness of aircraft, engine manufacturers are developing ceramic materials...

.... The overall validity of the approach was tested against several machines and presented in Ref. [ 10 ]. The above method was shown to be accurate for transient turbine operation. However, it is based on a function which does not distinguish between thermal radiation, natural convection, or forced...

... with the vacuum in the turbine cavity during the steam ingestion phase. Vacuum means the fluid expands and the fluid temperature drops below the metal temperature. Once the steam ingestion ends, the steam is replaced gradually by ambient air and the radiation from the hot parts (rotor and inner casing) prevails...

.... The peak intensity of CH* in IDF is higher than that in NDF. Moreover, the length of reaction region in NDF increases with O/C equivalence ratio ([O/C] e ) until it reaches a steady value, while in IDF the length decreased with the increase of [O/C] e . Combustion Energy Experimental Radiation...
