Mathematical modeling the effect of catalyst initial shape and the crack pattern in olefin copolymerization [PDF]
A two-dimensional (2D) single particle model for the copolymerization of propylene-ethylene with heterogeneous Ziegler-Natta catalyst is developed. The model accounts for the effects of the initial shape of the catalyst and carck/ pore patterns on the ...

Determination of the flow field in the phenomenon of falling of sediment particles in near-stagnant water using the two-dimensional Burger equation solution with the fully implicit finite difference method [PDF]
Physical processes are dependent on various parameters that are modeled in their mathematical language with their own equation. Since some nonlinear partial differential equations are so difficult to solve, hence obtain their analytical solution except ...

Determination of Particle Paths using the Finite-Element Method [PDF]
Abstract Large ice masses contain a wealth of information regarding past climates and atmospheric chemistry. To interpret properly information from ice cores obtained from glaciers, a time-scale for the ice core must be established.

Possibilities of the particle finite element method in computational mechanics [PDF]
We present some developments in the formulation of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems in fluid and solid mechanics accounting for fluid-structure interaction and coupled thermal effects. The PFEM uses an updated Lagrangian description to model the motion of nodes (particles) in both the fluid and the ...
