In this paper we review the concepts of the superalgebra, superderivation and some properties of them. We will define algebraic and differential superderivations on a superalgebra and will prove some theorems about them, Then we consider a superalgebra bundle, that is an algebra bundle which its fibers are superalgebras and then characterize the superderivations of the algebra of sections of th...

Abstract The detailed CFD simulation of the shell-side flow inside shell-and-tube heat exchangers results prohibitive for large-size components, due to large number tubes, together with multi-scale nature features. To overcome this issue, porous media approach can be adopted, substituting tube bundle a domain, where suitable momentum sink term in Navier-Stokes equation is provided. In paper, no...

Abstract Fluid blobs in an immiscible Newtonian fluid flowing a capillary tube with varying radius show highly nonlinear behavior. We consider here generalization of previously obtained results to non-Newtonian fluids. compute the yield pressure drop and mean flow rate two cases: (i) When single blob is injected, (ii) many are randomly injected into tube. find that effects emerge from non-unifo...
