A single-slope greenhouse (SSG) is the general name of a kind agricultural facility widely used in China. Microclimate studies for SSGs Weifang, Shandong Province, are relatively scarce. This paper mainly discusses test data nine including temperature, humidity, solar global radiation intensity, CO2 concentration, wind speed, and vapor pressure deficit (VPD) trend. Moreover, conservation quality method to estimate ventilation volume humidity growth after opening top vent greenhouse. Through...
Cavitation detection is particularly essential for operating efficiency and stability of pumps. In this work, to improve the accuracy identification, an approach combining wavelet packet decomposition (WPD) with principal component analysis (PCA) radial basic function (RBF) neural network introduced detect cavitation status centrifugal The performance interior flow‐borne noise are measured under three different flow conditions. Then, time‐frequency domain performed on signal using WPD,...
Gas–liquid two-phase flow directly determines the efficiency and stability of aeration tank. In this paper, a gas–liquid testbed is built to explore performance internal in an tank, including inverted-umbrella impeller (immersion depth 0 mm, rotational speed 250 r/min). Also, running process simulated by computational fluid dynamics (CFD) with population balance model (PBM), mass transfer coefficient compared experiment. The experimental results show that there big difference bubble...
In order to understand the aeration performance of inverted umbrella aerator and bubble characteristics in tank under different conditions, reveal internal relationship between performance, an experimental bench dissolved oxygen concentration high-speed photography was built. Logarithmic deficit values were fitted various conditions. The images captured by processed, then extracted accurately. It found that standard mass transfer coefficient increased linearly with increase rotational speed...
In order to reveal the details of internal flow in a centrifugal pump, large-scale mesh is needed. However, generated by serial grid algorithm cannot meet calculation requirements due huge amount time. A parallel generation pump for high-performance computers presented this paper. First, point set 3D Delaunay triangular on surface generated. Then, S-H (Sutherland–Hodgman) cropping and segmenting these sets employed. uniform boundary divided into different subregions. addition, ensure...
Abstract In this paper, the Eulerian model and Mixture are used to study free surface, internal flow mass transfer in aeration tank. The two multiphase models affect liquid velocity, oxygen coefficient (k L a) of than significantly higher simulates velocity near impeller, range main longitudinal circulation vortex is smaller model. error between simulated k a experimental value results show that more suitable for simulation gas–liquid two-phase
