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...

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...

Experimental study of multi-path ultrasonic flowmeters measurement accuracy in complex flow fields was carried out in the water flowrate standard facility of National Water Large Flowrate Measurement Station. Several muti-path ultrasonic flowmeters with different path arrangement were studied. The flow disturbances were created by bend, tapered pipe, diverging pipe and butterfly valve. By study...

This paper investigates the self-cleansing performance of an airlift pump with a U-bend. For this purpose, experimental setup is used to assess effect air flow on pump's ability lift water and remove particles under different submergence ratios particle concentrations. In addition, simple yet accurate fluid mechanical model interpret experiments individual predict critical velocity required for...
