An analytical equation of state (EOS) developed by Ihm-Song-Mason (ISM) has been applied tocalculate some thermophysical properties of molten polymers including Poly (1-octene) (PO), Poly (vinylmethyl ether) (PVME), Poly (vinyl chloride) (PVC), and Poly (styrene) (PS). Three temperature-dependentparameters of the ISM EOS have been determined based on the alternative scaling constants, dispersiv...

the objective of this work was to develop a new design of an intake manifold through a 1d simulation. it is quite familiar that a duly designed intake manifold is essential for the optimal performance of an internal combustion engine. air flow inside the intake manifold is one of the important factors, which governs the engine performance and emissions. hence the flow phenomenon inside the inta...

Most of the roads in Iraq are paved using Hot Mix Asphalt (HMA) which is consisted aggregates, asphalt cement and filler. In this study a laboratory investigation conducted two types widely used fillers highly locally available. Four different proportions are. Filler four proportion (i.e., 1.9%, 2.5%, 3.5%, 4.5%) by total weight aggregate for both used. These were blended with penetration 40/50...

In computer graphics, two types of geometric representations are widely used: surfaces and volumes. Surfaces are in nitely thin skins de ning the boundary of an object, and have been successful in modeling realistic appearances. However, their lack of information about the solid nature of objects make them inadequate for many applications. Volumes represent the entire solid geometry of an objec...

in the present study, the nonlinear model of non-newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. the model is carried out for axisymmetric, two-dimensional and fully developed blood flow. the vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. the cosine-shape stenosis convert to rigid artery by using a ...
