Dual fluidized bed gasifiers （DFBG） are effective in producing nitrogen-free syngas from biomass. How- ever, to improve the gasifier performance, pressure drops and solid fractions within the DFBG system need to be controlled. In this study, the effects of varying the fluidizing velocity in the fast fluidized bed （FFB） on the pressure drops and the solid fractions in the system were investigated in a 100 kW DFBG and in a dual fluidized bed cold model （DFCM）. Based on the experimental results, empirical correlations were developed to predict the height-averaged solid fraction in the bottom section of the FFB. Accuracy and advantages of the correlations were analyzed. The correlation is useful for design and modeling of the DFBG systems where the height-averaged solid fraction is required to be determined.

为了探究余热烟气中水蒸气对生物质烘焙及后续热解影响,该研究以榆木为研究对象,在立式炉中进行不同氛围(氮气及氮气-水蒸气)和不同温度(200、230、260、290℃)的烘焙试验,然后利用热重-质谱联用仪(TG-MS)和热裂解-色谱质谱联用仪(Py-GC/MS)进行惰性氛围的热解试验。结果表明:榆木在烘焙过程中发生了脱水、脱羰基、脱甲基反应,水蒸气的存在对后续热解油中乙酸的去除更有利。在所有样品中氮气氛围下290℃烘焙样品的失重速率峰值最低,仅为0.3%/℃。同时水蒸气的存在使氮气-水蒸气烘焙样品的最大失重峰后移。在热解主反应区,200、290℃烘焙温度下,水蒸气会提高热解反应活化能,而230、260℃烘焙温度下热解反应活化能却降低。此外,同一烘焙温度下水蒸气会抑制热解过程中H_(2)、CH_(4)、H_(2)O、CO和CO_(2)的生成。研究结果可为复杂气氛对生物质烘焙以及后续热解影响的研究提供参考。

Spanwise flexibility is a key factor influencing propulsion performance of pectoral foils. Performances of bionic fish with oscillating pectoral foils can be enhanced by properly selecting the spanwise flexibility. The influence law of spanwise flexibility on thrust generation and propulsion efficiency of a rectangular hydro-foil is discussed. Series foils constructed by the two-component silicon rubber are developed. NACA0015 shape of chordwise cross-section is employed. The foils are strengthened by fin rays of different rigidity to realize variant spanwise rigidity and almost the same chordwise flexibility. Experiments on a towing platform developed are carried out at low Reynolds numbers of 10 000, 15 000, and 20 000 and Strouhal numbers from 0.1 to 1. The following experimental results are achieved: (1) The average forward thrust increases with the St number increased; (2) Certain degree of spanwise flexibility is beneficial to the forward thrust generation, but the thrust gap is not large for the fins of different spanwise rigidity; (3) The fin of the maximal spanwise flexibility owns the highest propulsion efficiency; (4) Effect of the Reynolds number on the propulsion efficiency is significant. The experimental results can be utilized as a reference in deciding the spanwise flexibility of bionic pectoral fins in designing of robotic fish prototype propelled by flapping-wing.

This paper presents a numerical investigation of an active tip-clearance control method based on cooling injectionfrom the blade tip surface. It aims to study the influences of air injection on controlling tip clearance flow, withemphasis on the effects of the injection location on secondary flow and the potential thermal benefits from thecooling jet. The results show that injection location plays an important role in the redistribution of secondary flowwithin the cascade passage. Injection located much closer to the pressure-side comer performs better in reducingtip clearance massflow and its associated losses. However, it also intensifies tip passage vortex, due to less restraintderiving from the reduced tip clearance vortex. Lower plenum total pressure is required to inject equivalentamount of cooling air, but the heat transfer condition on the blade tip surface is a bit worse than that with injectionfrom the reattachment region. Thus the optimum location of air injection should be at the tip separation vortex region.
