This study presents a novel method to examine particle burnout in coal-fired utility boilers by extracting information from computational fluid dynamics (CFD) model results. The direct targeting of underlying causes enabled by this method can provide dramatic improvement in the unburned carbon in fly ash (carbon-in-ash or CIA), improving the commercial value of the ash as an additive in the production...
With respect to the measurement uncertainty, this paper discusses the definition, the sources, the classification and the expressions of the CFD uncertainty. Based on the orthogonal design and the statistics inference theory, a new verification and validation method and the related procedures in the CFD simulation are developed. With the method, two examples of the CFD verification and validation...
Mobile operating compartment with overpressure protection performance can provide a comfortable and safety environment for the patients and the surgical team by minimizing the risk of biochemical contamination through appropriate air filtration and air distribution scheme. The air pattern and temperature distribution inside a mobile operating compartment with overpressure protection performance were...
Integrated gasification combined cycle (IGCC) with carbon capture and storage (CCS) is a viable greenhouse gas control technology in using coal for power and/or hydrogen generation. This work describes the development of a pilot-scale pressurized entrained flow coal gasification facility and the parallel computational fluid dynamics (CFD) based simulation capability for the purpose of advancing commercial...
