| 1 | Study on Characteristics of Co-firing Ammonia/Methane Fuels under Oxygen Enriched Combustion Conditions显示文摘Having a background of utilising ammonia as an alternative fuel for power generation, exploring the feasibility of co-firing ammonia with methane is proposed to use ammonia to substitute conventional natural gas. However, improvement of the combustion of such fuels can be achieved using conditions that enable an increase of oxygenation, thus fomenting the combustion process of a slower reactive molecule as ammonia. Therefore, the present study looks at oxygen enriched combustion technologies, a proposed concept to improve the performance of ammonia/methane combustion. To investigate the characteristics of ammonia/methane combustion under oxygen enriched conditions, adiabatic burning velocity and burner stabilized laminar flame emissions were studied. Simulation results show that the oxygen enriched method can help to significantly enhance the propagation of ammonia/methane combustion without changing the emission level, which would be quite promising for the design of systems using this fuel for practical applications. Furthermore, to produce low computational-cost flame chemistry for detailed numerical analyses for future combustion studies, three reduced combustion mechanisms of the well-known Konnov's mechanism were compared in ammonia/methane flame simulations under practical gas turbine combustor conditions. Results show that the reduced reaction mechanisms can provide good results for further analyses of oxygen enriched combustion of ammonia/methane. The results obtained in this study also allow gas turbine designers and modellers to choose the most suitable mechanism for further combustion studies and development. | XIAO Hua WANG Zhaolin VALERA-MEDINA Agustin BOWEN Philip J | 2018 | Journal of Thermal Science2018，27，3： | 6 |
| 2 | Procedural complexity independent of P2Y12 reaction unit(PRU)values is associated with acute in situ thrombosis in Pipeline flow diversion of cerebral aneurysms显示文摘background Acute in situ thrombosis is an ischaemic phenomenon during Pipeline embolisation device(PED)procedures with potentially high morbidity and mortality.There is controversy regarding the role of platelet function testing with P2Y12 assay as a predictor of intraprocedural thromboembolic events.There is limited knowledge on whether procedural complexity influences these events.Methods Data were collected retrospectively on 742 consecutive PED cases at a single institution.Patients with intraprocedural acute thrombosis were compared with patients without these events.results A cohort of 37 PED cases with acute in situ thrombosis(mean age 53.8 years,mean aneurysm size 8.4 mm)was matched with a cohort of 705 PED cases without intraprocedural thromboembolic events(mean age 56.4 years,mean aneurysm size 6.9 mm).All patients with in situ thrombosis received intra-arterial and/or intravenous abciximab.The two groups were evenly matched in patient demographics,previous treatment/subarachnoid hemorrhage(SAH)and aneurysm location.There was no statistical difference in postprocedural P2Y12 reaction unit(PRU)values between the two groups,with a mean of 156 in the in situ thrombosis group vs 148 in the control group(p=0.5894).Presence of cervical carotid tortuosity,high cavernous internal carotid artery grade,need for multiple PED and vasospasm were not significantly different between the two groups.The in situ thrombosis group had statistically significant longer fluoroscopy time(60.4 vs 38.4 min,p<0.0001),higher radiation exposure(3476 vs 2160 mGy,p<0.0001),higher rates of adjunctive coiling(24.3% vs 8.37%,p=0.0010)and higher utilisation of balloon angioplasty(37.8% vs 12.2%,p<0.0001).Clinically,the in situ thrombosis cohort had higher incidence of major and minor stroke,intracerebral haemorrhage and length of stay.Conclusions Predictors of procedural complexity(higher radiation exposure,longer fluoroscopy time,adjunctive coiling and need for balloon angioplasty)are associated with acute thrombotic events during PED placement,independent of PRU values. | Bowen Jiang Matthew T Bender Erick M Westbroek Jessica K Campos Li-Mei Lin Risheng Xu Rafael J Tamargo Judy Huang Geoffrey P Colby Alexander L Coon | 2018 | Stroke & Vascular Neurology2018，3，3： | 2 |
