van der Waals gas modelThermomechanical processingAspect ratioCurrent theories involve the assumption of homogeneous bubble phase when describing the development of potassium bubble structure in K-Al-Si doped tungsten during thermomechanical processing. However, it follows from first principles that at ...

79with Becke–Johnson damping is employed to incorporate the interlayer van der Waals interaction and the structure is fully relaxed until the residual forces on each atom decrease to below 0.01 eV/Å. For electronic self-consistent calculations, we apply a convergence criterion of 10−6...
We take the Lennard-Jones (LJ) 12–6 model V(r)=4ε[(σ/r)12−(σ/r)6], with adjustable depth ε and zero-point distance σ, for a systematic exploration of van der Waals pentamers. For real clusters, we use the following model potentials: JDW42 for spin-polarized hydrogen ...
The meaning of VAN DER WAALS EQUATION is an equation that defines the physical state of a homogeneous gas, is a modification of the ideal-gas equation, and more nearly describes the properties of actual gases: (p + (a/v2)) (v—b)=RT where p is the pressu
Therefore, what the Van der Waals equation describes is the physical behavior in the low-temperature liquid and high-density region. In contrast to the ideal gas model, the Van der Waals equation may also describe the critical phenomena. Van der Waals' pioneering attempt greatly promoted the ...
van der Waals force n. A weak, short-range attractive force between atoms or molecules caused by their dipole moments, often arising in otherwise nonpolar atoms or molecules from a temporary shift of orbital electrons to one side of one atom or molecule. ...
In this work, an analytical analysis of the dynamics of a van der Waals gas flow passing through a direct shock wave was performed. For this purpose, modified Rankine-Hugoniot conditions were used. The influence of parameters α and β of the van der Waa
