Paraffin melting is widely used in the fields of phase change materials energy storage, gathering and transportation pipe-line paraffin removal, etc. Analysis mechanism influencing factors circular tube deeply has important guiding significance for improving heat storage capacity by changing structure material device ensuring safe crude-oil pipe-line. A double distribution lattice Boltzmann mod...
Macrosolen bidoupensis Tagane & V.S.Dang, sp. nov. (Loranthaceae) is newly described from Bidoup Nui Ba National Park in Lam Dong Province, southern Vietnam. The new species is characterized by small broadly elliptic to circular leaves, sessile to short petioles, slightly cordate to rounded leaf bases, 4-5 pairs of lateral veins and a basally green corolla tube. An illustration, a summary of DN...
We present an automatic method for computing an accurate parametric model of a piecewise defined pipe surface, consisting of cylinder and torus segments, from an unorganized point set. Our main contributions are reconstruction of the spine curve of a pipe surface from surface samples, and approximation of the spine curve by G1 continuous circular arcs and line segments. Our algorithm accurately...
In this paper, the problem of large pure bending deformations of membrane is considered. The membrane is a sector of torus with a closed cross-section. This membrane is called a curved tube for short. We consider the homogenous, incompressible, isotropic and hyperelastic material. The external load is a constant pressure and bending couples acting at the edges. The equilibrium equations reduce ...
