Coarse-graining Algorithms for the Eulerian-Lagrangian Simulation of Particle-laden Flows
H. Eshraghi, E. Amani, M. Saffar-Avval
In the present article, novel Coarse-Graining (CG) algorithms for the Eulerian-Lagrangian (EL) simulation of particle-laden flows are proposed. These include different variants of…
Alternative (Oriented) Singular Cochains and the Modified Cup Product
Taliya Sahihi, Homayoon Eshraghi, Ali Taghavi
A special subcomplex of the singular chain complex for a topological space, historically called oriented singular chain complex is used here with the new name "alternative" singula…
Biot-Savart helicity versus physical helicity: A topological description of ideal flows
Taliya Sahihi, Homayoon Eshraghi
For an isentropic (thus compressible) flow, fluid trajectories are considered as orbits of a family of one parameter, smooth, orientation preserving and nonsingular diffeomorphisms…
A new proof for the Banach-Zarecki theorem: A light on integrability and continuity
Ali Mahdipour-Shirayeh, Homayoon Eshraghi
To demonstrate more visibly the close relation between the continuity and integrability, a new proof for the Banach-Zarecki theorem is presented on the basis of the Radon-Nikodym t…
Multidimensional simple waves in fully relativistic fluids
T. Sahihi, H. Eshraghi, A. Mahdipour-Shirayeh
A special version of multi--dimensional simple waves given in [G. Boillat, {\it J. Math. Phys.} {\bf 11}, 1482-3 (1970)] and [G.M. Webb, R. Ratkiewicz, M. Brio and G.P. Zank, {\it…
Admissible Transformations and Normalized Classes of Nonlinear Schroedinger Equations
Roman O. Popovych, Michael Kunzinger, Homayoon Eshraghi
The theory of group classification of differential equations is analyzed, substantially extended and enhanced based on the new notions of conditional equivalence group and normaliz…
