Conveying hard and the abrasive materials has been one of the major operational problems in industrial situations. The erosion of plant components, especially the pipe bends by abrasive solid particles of a fluid stream makes installation of pneumatic conveying systems a very costly affair for industry. Most users have either lived with the problem or have employed expensive bend materials to r...
Numerical Investigation of Pressure Drop and Erosion Wear by Computational Fluid Dynamics Simulation
The modernization of computer technology and commercial computational fluid dynamic (CFD) simulation has given better detailed results as compared to experimental investigation techniques. CFD techniques are widely used in different field due to its flexibility and performance. Evaluation of pipeline erosion is complex phenomenon to solve by numerical arithmetic technique, whereas CFD simulatio...
Accurate prediction of erosion thickness is essential for pipe engineering. The objective of the present paper is to study the temperature distribution in an eroded bend pipe and find a new method to predict the erosion reduced thickness. Computational fluid dynamic (CFD) simulations with FLUENT software are carried out to investigate the temperature field. And effects of oil inlet rate, oil in...
Simulated stormwater management devices baited with alfalfa infusion were constructed to test conveyance pipe dimension and orientation as a potential deterrent to mosquito oviposition. Various configurations of pipe diameter, length, and orientation were evaluated based on egg raft counts. Field trials tested pipes of 1.3-, 5-, and 10-cm diam and 0-, 90-, or 270-cm lengths, in both horizontal ...
Pressure drop characteristics of turbulent flow through 90 degree pipe bends are numerically investigated by computational fluid dynamic simulation using k-ε RNG turbulence model with standard wall function. After the validation of present model against existing experimental results, a detailed study has been performed to investigate the pressure distribution and pressure drop characteristics o...
Flow in river bends is associated with generation of secondary flows that leads to a rather complicated flow pattern around bridge piers located the bend. In this study, patterns rectangular and oblong models collar at 90o angle 180-degree sharp bend an experimental plume were investigated. The 3D velocity data collected using Vectrino velocimeter. results indicated presence pier caused more in...
The gas pipelines usually undergo complicated and changeable regional environment. As the level of the potential difference or pipeline’s route changes in the space and therefore elastic bending cannot meet the needs when pipe changes its direction, we generally use pipe bend to connect two pipelines with different spatial extend direction during the pipe laying period, and it can reduce the te...
Perlakuan Panas atau biasa disebut dengan Heat Treatment, merupakan suatu proses memanaskan sebuah material (logam) temperatur tertentu dan kemudian didinginkan menggunakan media (misal: oli, air, air garam) kecepatan pendinginan yang ditentukan. Penelitian ini perlakuan panas quenching tempering pada pipa baja karbon API 5L diameter 16 inci (406.4 mm) ketebalan 1.437 (36.5 mana sebelumnya ters...
