Pre-heated isentropic gas in groups of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We confirm that the standard assumption of isothermal, shock-heated gas in cluster potentials is unable to reproduce the observed X-ray luminosity- temperature relation of groups of galaxies. As an alternative, we construct a physically motivated model for the adiabatic collapse of pre-heated gas into an isothermal potential that improves upon the ...

The 2D Finite Element Microstructure Evaluation of V-Shaped Arc Welding of AISI 1045 Steel
Metals, 2017 In the present study, V-shaped arc welding of the AISI 1045 steel is modeled by using 2D Finite Element Model (FEM). The temperature distribution, microstructure, grain growth, and the hardness of the heat-affected zone (HAZ) of the welding are simulated.

Journal of Thermal Science and Technology, 2009 In this study, an in-line pre-heating effect on the propagation of a laminar premixed flame in a two-dimensional channel is investigated numerically. An in-line pre-heating thickness of 1mm is generated by imposing uniform external high-temperature along

RELEASING THE WELDED PARTS THROUGH THERMAL TREATMENTS [PDF]
Fiabilitate şi Durabilitate, 2023 Heat treatments before welding are applied to steels in order to bring them to the state in which they can best support the welding operation (normalization, stress relief or recrystallization).
