The examined parameters include opening shape, opening size and opening position, load ratio, level of axial restraint and cross-section temperature distribution profile.
Cross-section temperature dependence is in very good agreement with that experimentally obtained by Dammeier and Friedrichs [J. Phys. Chem. A 114 (2010) 12963] using NCN3 pyrolysis in a shock tube followed by single-pass NCN absorption measurement, though their values differ by a factor of 2.6.
The simple method includes calculations of cross-section temperatures and ultimate load carrying capacities at elevated temperatures.
Figure 4 shows the altitude-latitude cross section of temperature amplitude (in Kelvin) and phase (in hour) of De3 for April (a) and August (b).
The selection of fuel cladding material is based on many design constraints, such as neutron absorption cross section, service temperature, mechanical strength, toughness, neutron radiation resistance, thermal expansion, thermal conductivity, and chemical compatibility.
Design method provided by EN1999-1-2 can give accurateate prediction of the ultimate strength of a short thin-walled aluminum alloy column with irregular shaped cross section at temperatures lower than 250 °C.
Temperature-optimized free Doppler kernel reconstruction significantly outperforms all previous interpolation-based methods, achieving 0.1% relative error on temperature interpolation of 238U total cross section over the temperature range [300K,3000K] with only 9 reference temperatures.
Failure modes of the thin-walled aluminum alloy column with irregular shaped cross section at ambient temperature and elevated temperatures in a fire were studied using a verified finite element model.
Results show that the channel cross section, inlet gas temperature, and reformer pressure have the largest effect on the reactor performance.
Figure 3 shows the cross section of the temperature amplitude (in Kelvin) and phase (in hour) of Dw1 as a function of latitude and altitude for March (a) and July (b) derived from eCMAM30 (left) and SABER (right).
