INTRODUCTION The paper presents a new multiscale framework that is both mathematically rigorous and practical in the sense that it has been successfully applied in aerospace, automotive and civil engineering industries. The “rigor” aspect of the method is provided by recently developed computational continua (C) formulation (Fish and Kuznetsov, 2009), which is endowed with fine-scale details, i...

Phase change material (PCM)-based thermal energy storage (TES) systems are widely used for repeated intermittent heating and cooling applications. However, such typically face some challenges due to the low conductivity expensive encapsulation process of PCMs. The present study overcomes these by proposing a lightweight, low-cost, resistance TES system that realizes fluid-to-PCM additively manu...

Biomass pyrolysis is a promising approach for producing economic and environmentally friendly fuels bioproducts. experiments show that feedstock properties have significant impact on product yields composition. Scientists are developing detailed chemical reaction mechanisms to capture the relationships between biomass composition yields. These can be computationally intensive. In this study, we...

in this paper, a new alternative method for order reduction of high order systems is presented based on optimization of multi objective fitness function by using harmony search algorithm. at first, step response of full order system is obtained as a vector, then, a suitable fixed structure considered for model order reduction which order of original system is bigger than fixed structure model. ...
