The first choice for imaging diagnosis of parathyroid gland (PTG) abnormalities is ultrasonography with a high-frequency probe. The patient must be positioned correctly when performing either imaging or percutaneous ethanol injection (PEIT) of the PTG. The enlarged PTGs are examined by ultrasonic tomography using 3D measurements, and it is important to evaluate blood flow; the PTGs are hypervas...

Abstract The turbine blade generally works in severe aerodynamic environments such as high temperature and pressure. Various forms of secondary flow, unsteady potential periodic wake the passage, strong interactions among these flow structures affect efficiency seriously. This paper performs a numerical simulation T106 cascade to investigate characteristics performance under interaction between...

in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with ai...

The unstable flow of a shaft tubular pump device (STPD) leads to energy loss, thereby reducing its efficiency. aim this study is investigate the distribution pattern loss in STPDs. This paper reveals that two components with highest proportion are impeller and outlet passage. Furthermore, turbulent entropy production primary cause loss. Due wall effect, mainly occurs near hub shroud. Additional...
