Experimental Study of Liquid & Sand Erosion in Pipe Lines
Mehdi Mohammadi Rahaghi
In this work the created erosion by the movement of two phase fluids in pipelines has been investigated. The main fluid is consisted of liquid and solid phase. The liquid phase is water, and the solid phase is sand particles. In this work, the effective parameters on erosion rate such as: fluid velocity, sand size, sand concentration, hardness and density of metal, have been studied. To find out the erosion rate, ring coupons of two kind of carbon steel and aluminium in six different location in pipe line (in accordance with operational production and oil material transition) have been employed.
At first, liquid erosion velocities (single phase) are measured in six locations. And in next stage, erosion of two phase fluid has been evaluated. In each stages, the data which are obtained from experiments are compared with available standard data and some recommendations are proposed. Then a mathematical model for evaluation of erosion rate by means of experimental data and use of genetic algorithm in MATLAB software (differential evolution method) has been presented. By comparison of mathematical model with experimental data, we find out that the proposed model is able to predict the experimental data with good Satisfaction.
Key words: sand erosion, ring coupon, erosion rate, genetic algorithm.
