Numerical Investigation on Effective Elastic Modulus of Multifractal Porous Materials
نویسندگان
چکیده
The design of a novel material necessitates fundamental understanding its structure–property relation. Inorganic porous materials (media) such as natural soil and rock, artificial ceramic cement, exhibit multifractal characteristics in view their structural heterogeneity. This paper presents numerical investigation the effective elastic modulus materials. Two types deterministic stochastic cascading algorithms are employed to synthesize fields, then mathematical formula is proposed perform conversion from intensity field local material. Furthermore, finite element method used achieve homogenization modulus. Special attention paid dependence on heterogeneity

A numerical investigation of phase change effects in porous materials
In this paper, a numerical study of heat and mass transfer with phase change in porous materials is performed. The problem is modelled by a system of transient inter-coupled equations governing the twodimensional multiphase transport process in porous media. The solution algorithm allows full simulation without any significant simplifications. The variations and the interrelationship between th...
متن کاملNumerical Investigation of Effective Parameters on Efficiency of Solar Chimney
The environmental pollution crisis caused by the excessive use of fossil fuels and the risk of the destruction of natural resources and reserves, as well as the excessive production of greenhouse gases and, consequently, global warming, led many energy researchers to use renewable energy As a fossil fuel alternative. Solar chimneys are one of the types of renewable energies that have been taken...

The drops are used to control the descents, stabilize the bed level, and control the upstream water level in sloping channels with less slope than the ground slope. The current study presents a numerical analysis of hydraulic characteristics in the vertical drop using computational fluid dynamics. At first, the laboratory models were used for verification and choosing the best model of turbule...
متن کاملEffective Elastic Modulus of Structured Adhesives: From Biology to Biomimetics
Microand nano-hierarchical structures (lamellae, setae, branches, and spatulae) on the toe pads of many animals play key roles for generating strong but reversible adhesion for locomotion. The hierarchical structure possesses significantly reduced, effective elastic modulus (Eeff), as compared to the inherent elastic modulus (Einh) of the corresponding biological material (and therefore contrib...
