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, ...

Background. According to the estimates of World Health Organization for 2021, 615 million people (about 10% population world) showed symptoms depressive or anxious disorders. Among main causes death in population, first half year continues suffer from diseases circulatory system, and forecasts indicate a savings trend an increase. Therefore, development anxiety-depressive disorders on aphids is...

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...

1. A new concept of endolymph flow in the vertebrate vestibular system is presented. This approach describes quantitatively the flow in the entire system of three semicircular ducts interconnected by the utriculus and the crus commune. This approach is quite distinct from the classical theory in which the labyrinth is generally conceived to consist of three separate duct circuits. 2. The presen...
