以纳米流体分频的光伏/光热(PV/T)集热器能使光伏和光热模块的工作温度解耦,从而获得更高的太阳能综合利用效率。以水基Ag-SiO_(2)纳米流体为分频液和集热工质,设计新型的分频PV/T集热器结构,研究在Ag-SiO_(2)纳米流体4种质量浓度和运行条件下,分频PV/T集热器功能单元的热、电性能。结果表明:Ag-SiO_(2)纳米流体的质量浓度显著影响PV/T集热器功能单元的性能,质量浓度为0.025%时,综合效率约为63.21%,比水为分频流体时的综合效率提升约38.04%;得出水基Ag-SiO_(2)纳米流体分频时PV/T集热器功能单元的热、电效率和综合效率与不同纳米颗粒质量浓度的拟合关系式,为通过控制纳米流体质量浓度参数从而调节PV/T集热器的热、电输出提供理论依据。

In tropical environments, most soybean growth studies have utilized rice husk biochar (RHB) in soil, even though it is low in nitrogen, potassium, and phosphorous. This may not give short-term agronomic performance relative to enriched biochar. Moreover, the impact of inoculating soybean seeds with atmospheric nitrogen-fixing bacterium Bradyrhizobium japonicum on nodulation and grain yield has produced inconclusive findings in the literature. This research therefore aims to assess the effect of poultry manure (PM), poultry manure biochar (PMB) and RHB alone and in combinations on grain yield, dry shoot and root biomass of soybeans in the semi-deciduous agro-ecological zone. In addition, the effect of B. japonicum inoculated and non-inoculated soybean seeds on nodulation and grain yield was also investigated. The treatments followed a split plot design studying inoculation and non-inoculation, soil amendments (eight), and control subplot factors, respectively. The results show that the amendment of a ferric acrisol with 4 Mg∙ha−1 PM, 10 Mg∙ha−1 RHB + 2 Mg∙ha−1 PM, and 5 Mg∙ha−1 RHB + 4 Mg∙ha−1 PMB with B. japonicum inoculated seed produced significantly greater grain yield (p = 0.05). PM treatment had a significant (p B. japonicum-inoculated soybean seeds significantly (p = 0.014) increased soybean nodulation. This study suggests that RHB combined with PM or PMB provides a beneficial source of N, P, and K, resulting in improved soybean yield and nodulation in a tropical ferric acrisol.

为了研究真实海域中振荡水柱(OWC)波能转换装置的水动力性能,本文基于势流理论和高阶边界元方法,建立了不规则波与岸基式OWC波能装置相互作用的二维非线性数值模型,不规则波基于JONSWAP谱生成。为了考虑由于水体黏性引起的能量耗散,在气室内水面边界条件中引入人工黏性阻尼。并在大连理工大学波流水槽中开展了物理模型试验,对数值模型的有效性进行了验证。研究发现,在不规则波作用下,OWC波能装置的水动力效率相较于规则波作用下有所降低,特别是在低频波区域效率差值最大。与规则波相比,不规则波浪作用下装置峰值效率对应的频率变大。气室内的相对水面高程随着有效波高的增加而降低,而气室内相对气压则随有效波高的增加而增大。OWC波能装置的水动力效率受有效波高的影响较小,其峰值效率对应的频率不受波浪非线性的影响。本文可以为OWC波能装置的设计提供参考。
