In the natural gas heating process, cylinder-type heater using water as an intermediate medium is most extensively used. The heat exchange rate between and fire tubes in great-capacity cylinder appears to be important element affecting a heater’s thermal efficiency. flow field within new diversion-type with vertical guide plate design described this paper. contrast prior research that concentra...

Abstract Based on the distribution and layer characteristics of prestressed steel wire-wound cylinder four-column hydraulic press, its supporting parts not only bear constant stress caused by internal pressure, but also withstand alternating cylinder, then produce gradual accumulation plastic deformation. This paper uses theoretical calculation formulas to solve corresponding parameters, establ...

Viscoelasticity weakens the asymmetry of laminar shedding flow behind a blunt body in free domain. In present study, this finding is confirmed by four unsteady viscoelastic flows with asymmetric configuration, i.e., over an inclined flat plate various angles incidence, rotating circular cylinder, cylinder slip boundary distribution, and row eight equally closely spaced cylinders (which can be c...

the effective factors of forward speed, cylinder rotation, and clearance between a combine’s cylinder and concave on wheat kernel breakage and seed germination were studied in karaj area using a 955 model john dear combine. this study was conducted on three levels of adjustment for each of the variables, 1.2, 1.8 and 2.5 km/hr for forward speed, 800, 900, 1000 rpm for cylinder rotation as well ...

In this article, we develop a new implicit constitutive relation, which is based on thermodynamic foundation that relates the Hencky strain to Cauchy stress, by assuming structure for Gibbs potential stress. We study tension/compression of cylinder, biaxial stretching thin plate and simple shear within context our relation. then compare predictions relation Ogden’s with experiments Treloar conc...
