Core-Line-Based Vortex Hulls in Turbomachinery Flows
نویسندگان
چکیده
In today's CFD-assisted turbomachinery design, a primary objective is to minimize the effects of vortices. Their automatic identification, along with other flow structures, in numerical data is a current research topic. This paper presents a novel method to find vortex hulls in turbomachinery flows automatically. Based on a vortex core line that is the centerline of the vortex, the method is able to locate bent vortices and to distinguish adjacent vortices in the complex flows. We experiment with the method on several practical flow data sets from the field of turbomachinery.

Investigation of vortex-induced vibration phenomenon in verticallong circular slender structure with non-uniform flows
Analyzing the vortex-induced vibration of a slender marine structure withlength to diameter ratio up to 200 is the objective of this study. This slender is free to move in both in-line and cross flow directions and immersed completely in water. Three different types of shear currents pass on it and cause to vibrate slender in different forms. Nowadays, these vibrations are very important for de...
متن کاملVortex core detection: back to basics
Analyzing vortices in fluid flows is an important and extensively studied problem. Visualization methods are an important tool, and vortex cores, including vortex-core axes, are frequently objects for which visualization is attempted. A robust definition of vortex-core axis has eluded researchers for a decade. This paper reviews the criteria described in some early papers, as well as recent pap...

To simplify the governing equations, two fundamental assumptions namely Low Mach Number and ...
متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
