Tip leakage vortex has an important influence on the performance of semi-open centrifugal pumps. Simulations based three-dimensional Reynolds-Averaged Navier–Stokes were conducted to study structural characteristics tip and its effects internal flow field, Shear Stress Transport k-ω turbulence model was used simulate whole passage pumps with clearances 0 mm 1 mm. Then, analyzed using relative vorticity transport equation. The numerical data experimental results agreed well. formed in...
The flow pattern of the forebay pumping station has a considerable effect on operating efficiency and stability pump unit. A good can enable unit to improve conditions. This study takes large as research object considers two rectification schemes, namely, single bottom sill “bottom + diversion pier”. Without facilities under different start-up after addition is calculated, influence combined analyzed. Results show large-scale undesirable structures such backflow vortex in original design...
A new contacting performance index, the global induced principal curvature (GIPC) is put forward in this paper, as well its calculation method. This index can be used to analyze characteristics within conjugating region of gearing, so that gearing understood. novel type named offset ZI worm drive laid out. The method applied gearing. GIPC calculated by numerical and verified analytical method, are analyzed. results show absolute value e-flank 52.2384% smaller than i-flank, which indicates...
Variants of Ectodysplasin A1 (EDA1) regulate the proliferation, migration, and odontogenic differentiation human dental pulp stem cells (hDPSCs). Further study these variants could reveal mechanism by which EDA1 induces tooth development. The following groups hDPSCs were studied: those expressing wild-type (Wt) EDA1, non-syndromic agenesis (NSTA) (NSTA-A259E, NSTA-S374R), a syndrome type (STA) variant (STA-H252L), transformed with empty vector (NC, negative control). proliferation was...
Holistic healthcare practitioners have now started to focus on specific traditional medicinal mushrooms treat rheumatoid arthritis (RA). Ganoderma lucidum (GL) is one of the oldest that been used in ancient Chinese medicine inflammatory ailments, including autoimmune diseases such as RA. Spores from this mushroom effects immunomodulation, aging, and cancer. However, effect G. spores (GLS) remains unclear. Therefore, we investigated GLS oil a collagen-induced (CIA) model. Metabolomics...
Ultrasound (US)-mediated cavitation of microbubbles has evolved into a new tool for organ-specific gene and drug delivery. This paper was to investigate the feasibility acidic fibroblast growth factor (aFGF) intravenous delivery ischemic myocardium rats by ultrasonic modified with heparin. Heparin (HMB) were prepared freeze-dried method. Acute myocardial infarction (AMI) model established cardio protective effect aFGF combing HMB (aFGF-HMB) under US-mediated technique investigated. aFGF-HMB...
The main objective of this article is to propose a practical methodology compute the induced curvature parameters for line-conjugated tooth surface couple based on normal vector its instantaneous contact line. computing formulae in different form are thus suggested preceding order convenient use. Based this, accordingly given out. Compared previous work, deducing process more rigorous and laconic, obtained results practical. Concurrently, techniques provided, beneficial development meshing...
Pump station engineering is a water conservancy project used for long-distance transfer, irrigation and drainage, urban living industrial supply. Centrifugal pumps are one of the main pump types commonly in pumping stations, their operation considerable importance safety, stability, efficient stations. This paper takes large with seven centrifugal units as research object combines experimental numerical simulation. The axial flow velocity uniformity, average cross-sectional deviation angle,...
A type of modified-hourglass worm gear drive, frequently called type-II gearing for short, has various favorable meshing features. Its sole shortcoming is the undercutting wheel. By adopting a slight modification, this problem can be overcome due to removal part one subconjugate area containing curvature interference limit line. To measure how effectively avoided, strategy determine point in most severe condition proposed drive. The presented consists two steps. first step establish system...
