A hybrid Monte Carlo molecular dynamics technique is developed that gives equations of motion for an isothermal system. Test results for a Lennard-Jones fluid are shown to be in good agreement with the known equation of state. The physical interpretation of the procedure and the extension to isothermal–isobaric systems is also discussed. © 2002 American Institute of Physics. @DOI: 10.1063/1.147...

in the present work the recrystallization behavior of deep drawing grade al-killed low carbon steel sheets produced by mobarakeh steel plant (msp) has been studied. salt bath isothermal annealing has been applied to cold rolled samples and the resulted microstrucrures have been compared with the microstructure obtained from the box annealing process in msp. it is found that at 635 and 700ºc the...

In this paper we discuss the incompressible limit for multicomponent fluids in isothermal ideal case. Both a direct limit-passage equation of state and low Mach-number rescaled PDEs are investigated. Using relative energy inequality, obtain convergence results densities velocity-field under condition that model possesses sufficiently smooth solution, which is granted at least short time. Moreov...

Research on the creep-thermomechanical fatigue (CTMF) behaviors of austenitic stainless steel for nuclear power plant pipelines is reviewed in present paper. The stress response behavior, main damage mechanisms, including thermomechanical fatigue, creep, oxidation, and dynamic strain aging (DSA), as well effects dwell type, time, temperature-strain phase angle life behavior under CTMF loading c...

The higher regularity estimate has been a challenging question regarding the Boltzmann equation in bounded domains. Indeed, it is well-known to have “the non-existence of second order derivative at boundary” Guo et al. (Invent Math 207:115–290, 2017) even for symmetric convex domains such as disk or sphere. In this paper, we answer affirmative by constructing $$C^{1,\beta }$$ solutions away fro...

The statistical behaviors of mean enstrophy and its evolution during head-on interaction premixed flames propagating toward a chemically inert flat wall across the turbulent boundary layer have been analyzed using direct numerical simulations for friction velocity-based Reynolds number [Formula: see text]. dynamics both isothermal adiabatic thermal conditions. contributions vortex-stretching vi...

We analyze a large number of high-order discrete velocity models for solving the Boltzmann-Bhatnagar-Gross-Krook equation for finite Knudsen number flows. Using the Chapman-Enskog formalism, we prove for isothermal flows a relation identifying the resolved flow regimes for low Mach numbers. Although high-order lattice Boltzmann models recover flow regimes beyond the Navier-Stokes level, we obse...

The role of isothermal aging on the localized corrosion behavior of Al90Fe5Gd5 and Al87Ni8.7Y4.3 alloys was characterized in 0.6 M NaCl solution. The pitting (Epit) and repassivation (Erp) potentials were both increased ~400 mV by the presence of transition and rare earth metal additions in supersaturated solid solution and amorphous structure. A statistical distribution in Epit observed on sma...
