This paper analyzes laminar viscous fluid flow through interstices in order to properly design the labyrinth seals and improve the volumetric efficiency of the turbomachines. The theoretical study and hydrodynamic modeling of the threedimensional flow inside the labyrinth was made using a CFD application ANSYS Fluent, on different labyrinth geometries. There were determined: the flow spectrum, ...

Thermoplastic use as labyrinth seals in rotating equipment is continuing to gain acceptance in the process industries. Presented in this paper is a discussion on thermoplastic use as a labyrinth seal material in centrifugal process compressors. Labyrinths made from engineering thermoplastics are used to improve efficiency, reliability, and installation time. An introduction to the polymer mater...

The paper presents an algorithm for planning the path of a mobile robot in a labyrinth. The algorithm uses an image, obtained by a camera. The algorithm processes the image to convert it into a matrix, presenting the labyrinth with obstacles and walls. Afterwards the algorithm finds the shortest path to a final target in the labyrinth. As opposed to the classical Dijkstra’s algorithm, the prese...

In this paper an artificial vision system for the analysis of the trajectory of an object is presented, which allows to solve a robotic labyrinth analyzing the routes of a moving object in the space. The prototype consists of a labyrinth with a unique solution at the center, so that regardless the position where a mobile object is placed, it is recognized and mapped to a coordinate system. Depe...

An altered vascular function may be related with several inner ear diseases such as Meniere’s disease, sudden deafness, and noise-induced hearing loss. The present study was aimed to visualize the cochlear blood-labyrinth barrier and to analyze angiogenic molecules in the cochlear vasculature. Murine cochlea was obtained and its bony shell was removed. Whole mount immunostaining of endothelial ...
