We present a strictly three-dimensional modeling technique as a basis for numerical simulations. These simulations range from a high-resolution indoor air flow modeling using the so-called thermal lattice Boltzmann method to a multi-zone network model for building energy simulation. Within this paper, an intermediate geometric model is derived from the IFC building product model standard with r...

This paper considers the design and optimization of thermal systems on the basis of the mathematical and numerical modeling of the system. Many complexities are often encountered in practical thermal processes and systems, making the modeling challenging and involved. These include property variations, complicated regions, combined transport mechanisms, chemical reactions, and intricate boundar...

in this paper, the problem of turbulent forced convection flow of water- alumina nanofluid in a uniformly heated pipe has been thoroughly investigated. in numerical study, single and two-phase models have been used. in single-phase modeling of nanofluid, thermal and flow properties of nanofluid have been considered to be dependent on temperature and volume fraction. effects of volume fraction a...

In this paper, recent numerical modeling and experiment work for predicting the effective thermal and mechanical properties of solid breeder blanket pebble bed materials is presented. The numerical modeling is based on the micro-mechanics displacement method in conjunction with an iterative process of successive releasing of the contact force of particles. Initial and final packed states for pa...

Thermal analysis of continuous and patterned multilayer films in the presence of a nanoscale hot spot" (2016). Thermal responses of multilayer films play essential roles in state-of-the-art electronic systems, such as photo/micro-electronic devices, data storage systems, and silicon-on-insulator transistors. In this paper, we focus on the thermal aspects of multilayer films in the presence of a...
