Zygomorphic flowers, with bilateral (dorsoventral) symmetry, are considered to have evolved several times independently in flowering plants. In Antirrhinum majus , floral dorsoventral symmetry depends on the activity of two TCP-box genes, CYCLOIDEA ( CYC ) and DICHOTOMA DICH ). To examine whether same molecular mechanism asymmetry operates distantly related Rosid clade eudicots, which asymmetric flowers thought independently, we investigated function a homologue LjCYC2 papilionoid legume,...
The increase of the thrust/weight ratio aircraft engines is extremely restricted by different 3-D flow loss mechanisms. One them corner separation that can form at junction between a blade suction side and hub or shroud. In this paper, in order to further investigate turbulent characteristics separation, large-eddy simulation (LES) conducted on compressor cascade configuration using NACA65 profiles (chord based Reynolds number: 3.82 × 105), comparison with previous obtained experimental...
Beamforming for rotating sound source localization (denoted by beamforming) is widely used in engineering nowadays. Acoustic shielding, such as shafts and covers, typically employed the practical measurement of localization. shielding blocks signal propagation between sources array, thus affects performance beamforming. However, detailed effects acoustic on beamforming are still unclear. In this study, blocking rate that represents degree path blockage defined first. The then investigated...
Optimal nitrogen (N) supply is critical for achieving high grain yield of maize. It well established that N deficiency significantly reduces and oversupply use efficiency without significant increase. However, the underlying proteomic mechanism remains poorly understood. The present field study showed reduced ear size dry matter accumulation in cob grain, directly resulting a decrease yield. content, biomass accumulation, variations were further analysed young ears at silking stage under...
In order to gain a better knowledge of the mechanisms and calibrate computational fluid dynamics (CFD) tools including both Reynolds-averaged Navier-Stokes (RANS) large eddy simulation (LES), detailed accurate experimental study corner stall in linear compressor cascade has been carried out. Data are taken at Reynolds number 382 000 based on blade chord inlet velocity. At first, flow boundary layer is surveyed using hot-wire anemometry. Then investigate effects incidence, measurements...
Identifications of rotating sound sources are interest in many industrial applications. Nowadays, almost all frequency-domain beamformings based on the concept virtual array (VRA), and consequently, have one constraint that microphones must constitute a ring around rotation axis source. This greatly restricts wide application these experiments. To overcome this constraint, paper proposed beamforming (mode composition beamforming, MCB). Without using VRA, MCB directly uses delay-and-sum with...
In order to gain a better knowledge of the mechanisms corner stall and calibrate computational-fluid-dynamics (CFD) tools including both Reynolds-averaged Navier-stokes large eddy simulation, detailed accurate experiment three-dimensional flow field through linear compressor cascade has been set up. Experimental data were acquired for Reynolds number 3.82 × 105 based on blade chord inlet conditions. First, conditions surveyed by hot-wire anemometry in boundary layers. Second, investigate...
Identifications of rotating sound sources are interest in many industrial applications. The most famous beamforming to identify source is the time-domain ROSI proposed by Sijtsma et al. (AIAA 2001-2167, 2001). Nowadays still unique widely recognized for array with arbitrary microphone configuration source. De-Dopplerisation essential a moving This paper devoted identification and elimination Doppler effect ROSI. A non-zero fundamental frequency may induce ghost contributions at other scan...
Large-eddy simulation (LES) is compared with experiment and Reynolds-averaged Navier-Stokes (RANS), LES shown to be superior RANS in reproducing corner separation the LMFA-NACA65 linear compressor cascade, terms of surface limiting streamlines, blade pressure coefficient, total losses suction side boundary layer profiles. However, too expensive conduct an influencing parameter study separation. approach, despite over-predicting separation, gives reasonable descriptions separated flow, thus...
The Merkel method, the Poppe approach, and an empirical equation are employed in developed computer program to predict evaporation loss for natural draft wet cooling tower (NDWCT). All three models validated with experimental results. calculation results NDWCT of a 300-MW power plant Luoyang show that both method could not make accurate prediction as approach does. annual water consumption economic benefits hybrid (NDHCT) calculated by using hourly weather condition. would save more than 95%...
