A two-dimensional ANSYS/Fluent computational fluid dynamics model is constructed of an existing experiment that consists of a square 8x8 array of heater rods within a square cross section pressure vessel filled with helium. The model includes heat generation and conduction within the rods, conduction and radiation heat transfer across the helium between the rods and enclosure, and the effective...

In this study, the wetting behavior of fluid onto horizontal square rod array is numerically investigated. The dimension referred to actual stator coil an automobile. computational parameters are gap and viscosity investigate dependency structure property. three-dimensional phase-field lattice Boltzmann method used both for flow phase transport. As increases, number area decrease, in axial dire...

The article deals with heat transfer through a rod small cross-section. is assumed to be so thin that the temperature at all points of its cross-section can considered same. When finding solution, power series decomposition method used. Formulas were derived not only for field, taking into account correction loss lateral surface rod, but also determining coefficient external and thermal conduct...

The Kirchhoff’s theory for thin, inextensible, elastic rods with nonhomogeneous cross section is studied. The Young’s and shear moduli of the rod are considered to vary radially, and it is shown that an analytical solution for the constitutive relations can be obtained for circular cross section and constant Poisson’s ratio. We comment on possible applications of our results.

In this article, we show that a class of high frequencies of the threedimensional linearized elasticity system in a thin rod and their associated eigenfunctions converge in a precise sense, as the area of the cross section of the rod goes to zero. The limit model is a coupled one-dimensional problem giving the classical equations for torsion and stretching modes in rods.
