The objective of this study is to find the temperature distribution of a slab as it moves through the pusher-type preheat furnaces. First, the imaginary planes method (IPM) as a new and applicable method for calculation of radiation heat transfer in industrial furnaces is studied, and the two-dimensional form of this method is used to calculate heat flux and temperature distribution in the furn...

Most of the work on behavior prediction in the eld of Qualitative Reasoning has focused on transient behavior and responses to perturbations; very little has been done regarding systems in steady state. A large class of systems, especially in the area of power systems, are designed for sinusoidal steady-state operation. Thus, an understanding of the steady state behavior of electrical circuits ...

  Abstract: The purpose of this study is to present a 2-D numerical model that solves the transient equations of flow, energy and species conservation in a single tubular solid oxide fuel cell (SOFC). Also an electrical model is considered to compute the electrical potential and current distribution in the cell. Using this comprehensive model the cell dynamic operation and response in a step lo...
