In gas-steam ejection power systems, the Al2O3 particles in combustion products can cause severe erosion on downstream elbow pipe. To calculate particle erosion, a modelling approach is developed by combining discrete phase model with flow-thermal coupling and introducing wall temperature parameters into model. Furthermore, influence of size, total pressure, mass flow rate was investigated. The...

Abstract The aim of this paper is to numerically investigate Vibration-Based Leak Detection (VBLD) method in pipeline systems based on Fluid–Structure Interaction (FSI) analysis predict leakages. In previous investigations, laboratory tests were widely used study the VBLD technique small-diameter water loop system pipes. current project uses Ansys Workbench extend these findings by integrating ...

Purpose: The purpose of this study is to investigate the relationship between myoelectric activities of wrist flexors and extensors and hand grip strength at four different positions of shoulder and elbow joints. Subjects: Thirteen normal male university students volunteered to participate in this study. Their mean ages, weights and heights were 19.6 (± 1.06) years, 75.9 (± 7.51) Kg and 173.5 (...
