LEAKAGE FAILURE ANALYSIS OF TUBE BUNDLE CONNECTION OF FLUE GAS WASTE HEAT RECOVERY DEVICE (MT) by REN ZiQi, DONG JinShan, FENG Jun, DING Yi

“…Firstly, the stress level of the waste heat recovery device under working condition was calculated by Ansys simulation software, and the maximum stress point was found at the tube sheet, and the stress value at the joint of tube sheet and heat exchange tube was larger.Then, macro-corrosion morphology analysis, metallographic microstructure analysis, micro-hardness test, scanning electron microscope（SEM） analysis of corrosion micro-morphology and EDS micro-area composition analysis of corrosion products were carried out on the sampling site of tube bundle leakage.The results show that, because of high temperature, increasing alkali concentration occurs at the crack of tube bundle. …”

Dark Atoms and the Positron-Annihilation-Line Excess in the Galactic Bulge by J.-R. Cudell, M. Yu. Khlopov, Q. Wallemacq

“…This explanation assumes that OHe, excited to a 2s state through collisions in the central part of the Galaxy, deexcites to its ground state via an E0 transition, emitting an electron-positron pair. The cross-section for OHe collisions with excitation to 2s level is calculated and it is shown that the rate of such excitations in the galactic bulge strongly depends not only on the mass of O-helium, which is determined by the mass of O--, but also on the density and velocity distribution of dark matter. …”
