Study on Pressure Drop Characteristics of Single Phase Turbulent Flow in Pipe Bend for High Reynolds Number
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...
متن کاملNumerical Simulation of Semi-Elliptical Axial Crack in Pipe Bend Using XFEM
In this work, XFEM is employed to obtain the stress intensity factors (SIFs) of a semi elliptical part through thickness axial crack. In XFEM, additional functions are employed to enrich the displacement approximation using partition of unity approach. Level set functions are approximated using higher order shape functions in the crack front elements to ensure the accurate modeling of the crack...
متن کاملDiaphragm in pressure pipe: Steady state head loss evolution and transient phenomena
With liberalization of European market, many high head power plants in Switzerland increase their potential generation to remain competitive. The existing surge tanks have to be modified to keep the flow management constant. A relevant way to limit the time of mass oscillation is to increase head losses at the entrance of a surge tank with an orifice. This study focuses on the influencing param...
متن کاملA shear and plantar pressure sensor based on fiber-optic bend loss.
Lower-limb complications associated with diabetes include the development of plantar ulcers that can lead to infection and subsequent amputation. While we know from force-plate analyses that medial/lateral and anterior/posterior shear components of ground-reaction forces exist, little is known about the actual distribution of these stresses during daily activities or about the role that shear s...
متن کاملNumerical Investigation of Temperature Distribution in an Eroded Bend Pipe and Prediction of Erosion Reduced Thickness
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...
