Error analysis of hydraulic radius evaluation in hydraulic calculation

چکیده
Hydraulic radius is an important parameter in hydraulic calculation. It often deemed that can be replaced by the cross-sectional average water depth when width to ratio ( B/H ) greater than a certain value traditional. Based on various artificial cross-section and natural ones, value-taking errors of are studied this paper. The results show it feasible adopt as rectangular section larger 40 or isosceles triangular 12. But for river, different level changes there no single-valued corresponding relationship between relative error . Therefore, we advise could not other variables calculation rivers.

Shape Effects and Definition of Hydraulic Radius in Manning 's Equation in Open Channel Flow
In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...
متن کاملTopological Analysis of Hydraulic Systems
The concept of a hydraulic axis plays a central role within the design and analysis of hydraulic systems. A hydraulic axis comprises working, control, and supply elements that realize a subfunction of a hydraulic system. Analyzing a system’s functional structure means to identify the hydraulic axes along with their couplings. The paper in hand addresses this problem; it presents concepts and al...
متن کاملEnergy Analysis of Hydraulic Fracturing
In this paper, numerical simulations of circular boreholes under internal hydraulic pressure are carried out to investigate the energy transferred to the surrounding rock and the breakdown pressure. The simulations are conducted by using a micromechanical continuum damage model proposed by Golshani et al. (2006). The simulation results suggest that the borehole breakdown pressure and the energy...

متن کاملParticle Swarm Optimization for Hydraulic Analysis of Water Distribution Systems
The analysis of flow in water-distribution networks with several pumps by the Content Model may be turned into a non-convex optimization uncertain problem with multiple solutions. Newton-based methods such as GGA are not able to capture a global optimum in these situations. On the other hand, evolutionary methods designed to use the population of individuals may find a global solution even for ...
