Continuum percolation threshold and ionic diffusivity of porous media consisting of asymmetrical ovoidal pores

Porous networks provide the main transport channels to the active media, which will damage the microstructure and then lead to a subsequent reduction in the strength, serviceability and aesthetic of porous materials. The connectivity of the porous network plays an essential role in the transport properties of these active media. In statistic...

Evolutionary Energy Performance Feedback for Design (EEPFD)

In order to understand the applicability of multidisciplinary design optimization (MDO) to the building design process, a MDO framework, titled Evolutionary Energy Performance Feedback for Design (EEPFD), along with the prototype tool, H.D.S. Beagle, were developed to support designers with the incorporation of partially automated performance...

Using Smart Controlled AC and Ceiling Fan to Save Energy

This research aimed to explore the energy savings through the use of smart control as well as ceiling fan in intelligent building. As the energy consumption of air-conditioning (AC) accounts for about 40% of total residential energy, therefore, applying smart control system to the use of AC to achieve the effects of comfy and energy savings...

A Robust Flux Splitting on Simulation of Transient Cavitated Flows Based On Single and Two Fluid Models

In this paper, a modification of pressure-velocity diffusion terms in AUSMDV is proposed to compute the compressible cavitated liquid-gas flows. As we know, cavitation phenomena are widely seen in multi-phase flow with different sizes of time and length scale. An accurate resolution of multi-scale phenomena such as material interfaces, contact...

The parallel implementation of forward-reverse estimator

Last several years the ship accidents caused the serious ecological catastrophes in the seaside of different countries. To prevent or, at least, reduce the possible damage due to accidents we need to develop efficient and accurate model for the simulation of the pollution spreading. The movement of the pollutant can be modeled by using a random...
