In the present work, a modified equation of state has been presented for the calculation of volumetric properties of supercritical fluids. The equation of state is van der Waals basis with temperature and density-dependent parameters. This equation of state has been applied for predicting the volumetric properties of fluids. The densities of fluids were calculated from the new equation of state...

In this study the thermal conductivity and the volumetric heat capacity of non-Newtonian fluids are investigated. These fluids find many applications in chemical, medical and food industries. They mostly have viscoelastic behavior and generally differ from Newtonian fluids. Two non-Newtonian fluids, solutions of xanthan and carboxy methyl cellulose in water with various concentrations have bee...

The animation of delicate vortical structures gas and liquids has been great interest in computer graphics. However, common velocity-based fluid solvers can damp the flow, while vorticity-based suffer from performance drawbacks. We propose a new solver derived reformulated Euler equation using covectors. Our method generates rich vortex dynamics by an advection process that respects Kelvin circ...

the present experimental study reports on enhancement of heat transfer by addition of nanoparticles to the working fluid of commercial swimming pool heat exchangers under laminar flow condition. three different concentrations of titanium dioxide nanoparticles were added to the water as working fluid of a typical forced convective heat exchanger used to transfer heat to public swimming pools. th...

background: phthalates are widely used as plasticizers in polyethylene terephthalate (pet) products. several pharmaceutical products have been stored in pet containers, and due to serious health effects of phthalates, migration levels of them into pharmaceutical products must be determined. in the present study, leaching levels of four common phthalate esters including di-n-butyl phthalate (dbp...
