| 4 | CFD study of non-premixed swirling burners: Effect of turbulence models显示文摘This research investigates a numerical simulation of swirling turbulent non-premixed combustion.The effects on the combustion characteristics are examined with three turbulence models:namely as the Reynolds stress model,spectral turbulence analysis and Re-Normalization Group.In addition,the P-1 and discrete ordinate(DO)models are used to simulate the radiative heat transfer in this model.The governing equations associated with the required boundary conditions are solved using the numerical model.The accuracy of this model is validated with the published experimental data and the comparison elucidates that there is a reasonable agreement between the obtained values from this model and the corresponding experimental quantities.Among different models proposed in this research,the Reynolds stress model with the Probability Density Function(PDF)approach is more accurate(nearly up to 50%)than other turbulent models for a swirling flow field.Regarding the effect of radiative heat transfer model,it is observed that the discrete ordinate model is more precise than the P-1 model in anticipating the experimental behavior.This model is able to simulate the subcritical nature of the isothermal flow as well as the size and shape of the internal recirculation induced by the swirl due to combustion. | Erfan Khodabandeh Hesam Moghadasi Mohsen Saffari Pour Mikael Ersson Par G.Jonsson Marc A.Rosen Alireza Rahbari | 2020 | Chinese Journal of Chemical Engineering2020,28,4: | 1 |

| 6 | Transition metal carbides as cathode supports for PEM fuel cells显示文摘As energy demands increase and environmental issues loom,fuel cells(FCs)have attracted significant attention as an alternative to conventional energy sources.Their use encompasses portable applications,transportation,and a stationary grid-power mainly due to their low-temperature operation and quick start-up.However,the primary challenge is improving fuel cell durability to meet 2025 U.S.Department of Energy targets(e.g.,8,000+h for automotive drive cycle).Proton exchange membrane fuel cell(PEMFC)catalysts currently suffer from low durability,undermining their wide-scale deployment into the consumer and industrial markets.Platinum group metals(PGMs)are still the most common catalysts used in PEMFCs as they provide among the highest activity for electrode reactions and lifetime stability.An effective way to decrease Pt loading is the adoption of supports to enhance both Pt dispersion and its durability.Corrosion of the carbon-based support was identified to be the major contributor to performance degradation as they suffer from parasitic oxidation to CO_(2)(at the cathode).Therefore,there is a significant interest in exploring stable alternatives to replace carbon supports in PEMFCs.Transition metal carbides(TMCs)have attracted significant attention over the last several years as a possible candidate to replace carbon-based catalyst supports in fuel cells.Despite these advantages over carbon supports,the large-scale deployment of TMC-based supports in fuel cells is still hindered by concerns of durability at the high potential on the cathode during start-up and shutdown operation.Here,we address the most relevant studies concerning TMCs as supports for acidic oxygen reduction reaction(ORR)catalysis,including viewpoints about the surface and bulk design of the support,as well as the design of the catalyst itself to enhance the interaction and dispersion with the support. | Eliran R.Hamo Brian A.Rosen | 2022 | Nano Research2022,15,12: | 0 |
| 7 | Special Column on Recent Advances in PCMs as Thermal Energy Storage in Energy Systems显示文摘Thermal energy storage technology has the advantages of high energy storage density,small size,and high energy conversion efficiency.It is one of the key energy storage technologies and an important way to achieve carbon peaking and carbon neutrality goals.Phase change materials (PCMs) offer this opportunity to store high amount of energy and release it in the form of latent heat when needed,and therefore have the advantage of being capable to alleviate the intrinsic intermittency of renewable power production,especially in wind and solar farms. | Mohammad Hossein AHMADI Tingzhen MING Marc A.ROSEN S.A.SHERIF Mohammad Mehdi RASHIDI | 2024 | Journal of Thermal Science2024,33,2: | 0 |
| 8 | 用新的热电联产程序对燃气蒸汽发电厂的总效用整合(英文)显示文摘A steam power plant can work as a dual purpose plant for simultaneous production of steam and elec-trical power. In this paper we seek the optimum integration of a steam power plant as a source and a site utility sys-tem as a sink of steam and power. Estimation for the cogeneration potential prior to the design of a central utility system for site utility systems is vital to the targets for site fuel demand as well as heat and power production. In this regard, a new cogeneration targeting procedure is proposed for integration of a steam power plant and a site utility consisting of a process plant. The new methodology seeks the optimal integration based on a new cogenera-tion targeting scheme. In addition, a modified site utility grand composite curve(SUGCC) diagram is proposed and compared to the original SUGCC. A gas fired steam power plant and a process site utility is considered in a case study. The applicability of the developed procedure is tested against other design methods(STAR? and Thermoflex software) through a case study. The proposed method gives comparable results, and the targeting method is used for optimal integration of steam levels. Identifying optimal conditions of steam levels for integration is important in the design of utility systems, as the selection of steam levels in a steam power plant and site utility for integration greatly influences the potential for cogeneration and energy recovery. The integration of steam levels of the steam power plant and the site utility system in the case study demonstrates the usefulness of the method for reducing the overall energy consumption for the site. | Sajad Khamis Abadi Mohammad Hasan Khoshgoftar Manesh Marc A.Rosen Majid Amidpour Mohammad Hosein Hamedi | 2014 | Chinese Journal of Chemical Engineering2014,22,4: | 0 |
