Correlation between pipe bend geometry and allowable pressure in pipe bends using artificial neural network

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Drilling Stuck Pipe Prediction in Iranian Oil Fields: An Artificial Neural Network Approach

Measurements and computations of flow in pipe bends

Measurements are given of the tiotal pressure and yaw relative to the pipe axis of flow in various pipe bends attached to the end of a long straight pipe, for a pipe Reynolds number of 2-36 x lo5. The behaviour of the induced secondary flows is presented in detail. In a 180" bend it is found that, from the start of tho bend, the secondary flows increase to a maximum and then decrease to a stead...

Corrosion and scaling in Bandar Abbas Pipe water network

Introduction: Scaling and corrosion is one the most important indices in water quality evaluation. Occurrence of scaling or corrosion may create disorder in economy of water and wastewater industry. In addition, corrosion produces by - products in water leading to health problem and reduction of water pipe life-time. In this study, the condition of scaling and corrosion in Bandar Abbas wa...

Flow Variables Prediction Using Experimental, Computational Fluid Dynamic and Artificial Neural Network Models in a Sharp Bend

Bend existence induces changes in the flow pattern, velocity profiles and water surface. In the present study, based on experimental data, first three-dimensional computational fluid dynamic (CFD) model is simulated by using Fluent two-phase (water + air) as the free surface and the volume of fluid method, to predict the two significant variables (velocity and channel bed pressure) in 90º sharp...
