Turbulent Kinetic Energy Distribution around Experimental Permeable Spur Dike

نویسندگان

چکیده

The spur dike is widely used in the waterway renovation project upper reaches of Yangtze River as a remediation structure, but its water destruction very common, and influence permeable characteristics riprap on stability has been neglected many studies. Through method combining generalized flume test theoretical analysis, submerged degree dike, porosity body, size void nearby turbulent kinetic energy studied. results show that front increases with increase degree, decreases porosity, first then pore size. At axis In rear area firstly research are great significance to further understanding age can provide scientific guidance for design restoration dikes.

investigation on time variation of scour around t shape spur dike in a 90 degree bend

spur dike is an important element for protection of river banks. spur dike causes variations in flow field, sediment transport and bed topography. the mechanism of flow and sediment transport in a channel bend is very complex, especially when a spur dike is constructed in a bend. in this paper the time variations of dimension of the scour hole and the bed’s topography were considered around a t...

Numerical and experimental assessment of turbulent kinetic energy in an aortic coarctation.

The turbulent blood flow through an aortic coarctation in a 63-year old female patient was studied experimentally using magnetic resonance imaging (MRI), and numerically using computational fluid dynamics (CFD), before and after catheter intervention. Turbulent kinetic energy (TKE) was computed in the numerical model using large eddy simulation and compared with direct in vivo MRI measurements....

Turbulent kinetic energy in normal and myopathic left ventricles.

PURPOSE To assess turbulent kinetic energy (TKE) within the left ventricle (LV) of healthy subjects using novel 4D flow magnetic resonance imaging (MRI) methods and to compare TKE values to those from a limited group of patients with a spectrum of dilated cardiomyopathy (DCM). MATERIALS AND METHODS 4D flow and morphological MRI data were acquired in 11 healthy subjects and 9 patients with dif...

Optimization of the Geometric Parameters of the Protective Spur Dike using Taguchi Method and GRA.

In general, engineering designs need to optimize the factors affecting the under-study phenomenon; however, this is often a costly and time-consuming process. In this regard, new methods have been developed to optimize with fewer tests; thus, they can make the whole process more affordable. In this study, Taguchi and Taguchi-GRA methods were used to design the geometric parameters of the protec...

Stepped Spillway Performance: Study of the Pressure and Turbulent Kinetic Energy versus Discharge and Slope

In the present study, flow over flat and pooled stepped spillways was simulated three dimensionally. The VOF method and k- ε (RNG) turbulent model was used to simulate the flow over the stepped spillway. The results indicated that the numerical model was acceptably capable of simulating the flow over the pooled and flat stepped spillways for different discharges. Following that, the effect of d...
