The location, size and reflection characteristics of bond-line voids of a titanium alloy superplastically formed and diffusion bonded (SPF/DB) test specimen were detected by a high resolution 50MHz ultrasonic C-scan system. These voids were undetectable using conventional ultrasonic inspections. Pre ...
These solve the averaged Navier–Stokes equation and parameterize turbulence using different schemes, which entail diffusion coefficients and turbulent kinetic energy. The equations are solved on different nested grids. The resolution of the inner grid is usually two kilometres, while the ratio between ...

I wanna define nonreflecting boundary condition for numerical simulation on wall. I know we can absorb wave with porous wall but i wanna define a boundary condition which absorb shock wave without mass diffusion. Do you have any experience about it? could you please help me about it. I try...
Based on current theories of diffusion and creep cavity closure at high temperatures, atheoretical analysis of diffusion bonding under super-plastic condition for Ti-6Al-4Vtitanium alloy is carried out. The diffusion bonding is mainly described as a two-stageprocess:1 The shrinkage process of ...
as well as accelerated aging experiments at temperatures in the range of these transitions, may be affected by significant errors [24], as the oxidation mechanism changes as crystalline domains are formed and grow with decreased temperature; (iii) the occurrence of limited oxygen diffusion processes...
The diffusion of both H2O and SO2 through the zeolite framework can potentially be attributed to two concomitant factors: increased hydration of 13X at 45RH% or higher sulfur uptake during the FGD process. To gain further insight into the two systems, thermogravimetric (TG) and microchemical EDS...
