Comparison of computed and measured particle velocities and erosion in water and air flows

Analysis on the erosion and side exchange of pipeline in the whole life cycle

“…The pipe is divided into three parts. The maximum erosion ratio is taken as the average erosion ratio in the area, and the wear thickness of the three parts is calculated by the formula (6) . Then the service life of pipe consists of the three parts, which are the time of rotating before, the time of rotating once at an angle of 120 ° and the time of rotating twice at an angle of 120 °.The specific erosion ratio can be available from Fig.2 (2) (3) (4).…”

“…Oka Y I [4] [5] changed the important parameters by the experiments to research the law of the erosion wear and put forward the erosion wear prediction equation. In China, Zhang Y and others [6], respectively, used the two methods of experimental research and numerical calculation to study erosion wear. Sun Haijiang and Ou Guofu [7] et al studied the erosion for 90 ° circular cross section of multiphase flow elbow in coal liquefaction by numerical investigation.…”

Numerical investigation of flow erosion and flow induced displacement of gas well relief line

“…Carrying fluid properties, particle content and particle size have been recognized as the significant factors for erosion (Tang et al, 2009;Ferng and Lin, 2010). And several models have been proposed based on experiments for single-phase liquid or gas flow contained solid particles (Zhang et al, 2007;Oka and Yoshida, 2005). However, most of these researches concern incompressible fluid flow in atmospheric pressure or low pressure environment, such as pneumatic conveying and slurry transportation.…”

A Semi-Empirical Airborne Particle Erosion Model for Polyesteric Matrix Fiberglass Composites

“…However, as is the case with most engineering applications, the main interest is focused on the global effects rather than the explanation of the process, therefore, CFD software have implemented erosion models Ref [16] for this particular task Ref [17]. It is one of the purposes of this paper to provide a simple mathematical relation that can be used for estimating the erosion rate in a similar way.…”
