fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

Abstract Organic Rankine Cycles transform low-temperature heat from sustainable sources into electrical power. Exploiting the full potential of a source requires optimal combination and working fluid. Today, fluids are commonly pure components. However, mixtures can significantly improve process efficiency due to their favorable temperature-glide during evaporation condensation. In this work, w...

the compressibility factor of nonassociated chain molecules composed of hard convex core yukawa segments was derived with saft-vr and an extension of the barker-henderson perturbation theory for convex bodies. the temperature-dependent chain and dispersion compressibility factors were derived using the yukawa potential. the effects of temperature, packing fraction, and segment number on the com...

ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported recently in this journal. The present paper describes two major software enhancements to TDE: (1) generation of equation of state (EOS) representations on demand and (2) establishment of a dynamically updated experimental data resource for use in the critical evaluation pr...

Molecular dynamics (MD) simulations are performed to study the sorption and transport properties of CH4 CO2 in amorphous polyethylene at temperatures from 350 600 K pressures up 500 bar. The uptake by generally increased with increasing pressure decreasing temperature. However, high pressures, for example, methane increases self-diffusion coefficients carbon dioxide increase pressure. These res...

The interfacial property of H2O+CO2+oil three-phase systems is crucial for CO2 flooding and sequestration processes but was not well understood. Density gradient theory coupled with PC-SAFT equation state applied to investigate the tension (IFT) (hexane, cyclohexane, benzene) under conditions (temperature in range 323–423 K pressure 1–10 MPa). IFTs aqueous phase+vapor phase were smaller than H2...
