The end wall loss of modern highly loaded low pressure turbine (LPT) has been greatly increased, due to the enhanced secondary flow and boundary layer separation loss. Thus, it is great significance develop effective control strategies improve condition aerodynamic performance LPT. This research carried out a numerical investigation on coupled strategy, which combined non-axisymmetric contouring (NEC) root tangential lean (RTL), based LPT cascade (Zweifel = 1.59). Meanwhile, optimization...
ABSTRACT Digestive system tumor, including esophageal gastric intestinal liver pancreatic and cholangiocarcinoma, are the most common tumors worldwide serve as a major cause of tumor‐related death. Cancer stem cells (CSCs) small group in that harbor self‐renewal, differentiation abilities, playing crucial role tumor initiation, progression, metastasis, supposed to be fundamental recurrence after conventional treatment. A comprehensive understanding targeting CSCs is key overcoming tumors. In...
When different images are presented to two eyes, they compete for perceptual dominance, such that a region of one image is visible while corresponding the other suppressed. This visual phenomenon called binocular rivalry. Binocular rivalry may be introduced in stereoscopic natural scene, leading strong discomfort and fatigue. differences exceed threshold, occurs. difference threshold regions increases with background complexity region. Based on these features human system, we proposed...
The present study aims to enhance the comprehension of flow field near casing an isolated rotor in a small-scale high-speed axial compressor. To achieve this objective, steady three-dimensional viscous calculations are employed obtain fields under different operational conditions. validate accuracy computations, comparison is made between numerical results and existing measured data, revealing favorable agreement. Then, using experiment measurements simulation, pressure signals flowfields at...
Abstract Modern low pressure turbines (LPT) always suffer from unexpected endwall flow losses due to the enhanced aerodynamic load. Thus, there is a demand for much more efficient methods improve performance of modern LPT. In this paper, novel control method (denoted by FILLET&NEC) which combines leading edge fillet configuration FILLET) and non-axisymmetric contouring NEC) was applied an ultra-high-loaded LPT cascade REF, Zweifel = 1.59) explore its potential underlying mechanisms...
Multivariate time series anomaly detection is a crucial application in the domain of data mining. Techniques for based on deep learning have made great progress, but they still some limitations. Existing methods cannot deeply mine potential correlation between data, there an imbalance performance efficiency and training optimization, also lack interpretability anomalies. It necessary to significantly enhance model's capacity detection. Therefore, two are proposed. Firstly, method graph...
Tandem impeller configuration has the potential to improve performance of highly loaded transonic centrifugal compressors, while related research is still in early stages and general design guidelines, such as selection inducer meridional length, are limited so far. In this paper, a compressor with various tandem configurations numerically investigated. The objective evaluate impact length [Formula: see text] on flow structure performance, further look into underlying mechanisms principles...
A highly loaded transonic centrifugal compressor is aerodynamically designed and numerically investigated. The objectives are to improve the efficiency by using tandem impeller configuration 3D free-formed blade design concepts. This approach has potential control both distorted flows within passages. results suggest that employing can significantly 1.4%. gain mainly contributed improved uniformity of discharge flow achieved when newly generated inducer shedding vortices rearrange secondary...
