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&...

CFD flow analysis of the cantileverR micro-turbine

The article deals with a description of results from research and development of the cantilever micro-turbine designed for the ORC power plants. The experimental turbine stage and used numerical models are briefly described. In the first part the comparison of measured and CFD resu...

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...

A study of hydrodynamically lubricated contact between axial rings of a high-speed gearbox

The pressure field and losses in hydrodynamically lubricated contact between axial rings of the pinion and the wheel of a high-speed gearbox under steady-state loading are investigated. For that reason a computer program was developed to numerically solve the general Reynolds and energy...

Preliminary Computational Study of Centrifugal Compressor Inlet Flow Instabilities with Radial Inlet Guide Vanes

The paper presents the research of flow instabilities in the inlet part of a centrifugal compressor channel equipped with radial inlet guide vanes. A simplified model is created and for that, a dimensional analysis of the flow is carried out. Methods of computational fluid dyn...

Numerical Simulations of Flow in Electrostatic Precipitators

Electrostatic precipitators are widely used in power generation and industry to separate solid particles from flue gases. They need relatively homogeneous distribution of the flue gas inside otherwise the required efficiency cannot be ensured. The paper shows how to approach some of pos...
