A comparison between linear and exponential schemes in control volume finite element method

H. Abbassi, A. Boughamoura, S. Ben Nasrallah

In this paper, we present a comparison of linear and exponential interpolation functions for control volume finite element method. The exponential interpolation function is…

Process modeling of composites by resin transfer molding: practical applications of sensitivity analysis for isothermal considerations

B.J. Henz, K.K. Tamma, R. Kanapady, N.D. Ngo, P.W. Chung

The resin transfer molding process for composites manufacturing consists of either of two considerations, namely, the fluid flow analysis through a porous fiber preform where the…

Application of the conservation element and solution element method in numerical modeling of heat conduction with melting and/or freezing

A. Ayasoufi, T.G. Keith

The conservation element and solution element (CE/SE) method, an accurate and efficient explicit numerical method for resolving moving discontinuities in fluid mechanics problems…

A non‐linear model of cerebral diffusion: stability of finite differences method and resolution using the Adomian method

M.J. Pujol, P. Grimalt

This paper describes a non‐linear reaction‐diffusion equation, which models how a substance spreads in the surface of the cortex so as to avoid a massive destruction of neurones…

Study and modelling of a density dependent population using faltung (closed cycle type) equations

Cèsar Bordehore, Angela Pascual, Maria J. Pujol, Julio Escolano, Inmaculada Manchón, Pedro Grimalt

Faltung equations (closed cycle type) have a wide range of biological applications, nonetheless, they are poorly studied. We use a Volterra‐Kostitzin model (which is a Faltung…

Effect of space ratio and corrugation angle on convection enhancement in wavy channels

G. Comini, C. Nonino, S. Savino

By neglecting the influence of tubes, this paper adopts a simplified two‐dimensional approach to deal with laminar convection of air through wavy finned‐tube exchangers. Pressure…
