Modelling fluid flow and heat transfer tasks for testing PIR motion sensor

The aim of this paper is to describe the methodology of modelling fluid flow and heat transfer tasks for testing electronic motion sensors, especially PIR (passive infra-red) motion sensors. The motion sensor measures changes in electromagnetic radiation in the infrared range caused by&...

Design of the levers at the development of new self-equalizing thrust bearings

Plain bearings are undoubtedly one of the essential parts of turbines and compressors. However, there are many cases in which asymmetric load occurs on the bearings due to thermal deformations, production inaccuracies or a simple deflection of the shaft. The presented research deals...
