The paper presents chosen experimental and model methods of investigating heat transfer
in a steel porous charge. The results of this investigation provide information on both the …

In industrial processes electrical motors are serviced after a specific number of hours, even if
there is a need for service. This led to the development of early fault diagnostic methods …

Recognition of states of electrical systems is very important in industrial plants. Article
describes a recognition method of early fault detection of DC generator. The proposed …

Transport phenomena of heat in porous media have been focus of many investigations.
Most studies deal with low-porosity granular media. A specific example of such a medium …

Currently, the metallurgical industry in Poland is struggling with the problem of the energy
use of process by-products. Coke oven gas (COG) or blast furnace gas (BFG) in accordance …

A method to obtain a radiation exchange factor FR in the bundle of steel round bars is
presented. This parameter is required for determination of the radiative thermal conductivity …

During the heat treatment of square or rectangular steel sections, a heated charge, arranged
in regular packages, is placed inside a furnace. This type of charge forms a porous medium …

The paper presents investigations devoted to the analysis of the thermal contact conduction
in a bundle of round steel bars. The phenomenon can be expressed quantitatively with the …

In many cases of heat treatment of steel products, the heated charge has a porous structure.
The examples of such charges include bundles of long steel components eg, bars. The …
