Artysta nowoczesny jako T.W.
No full textThe author analyses archival materials from IPN (Instytut Pamięci Narodowej – The Institute of National Remembrance) concerning a painter nicknamed ‘Tadeusz’. In 1973–1979, ‘Tadeusz’ was active as secret collaborator (t.w. – ”tajny współpracownik”) of SB (Służba Bezpieczeństwa – Interior Ministry Security Service). IPN documents contribute to the mapping of Polish art of the 1970s only to a limited extent. Nevertheless, they can form a basis for posing questions on artists’ collaborations with SB. The author claims that the acceptance of collaboration with SB was grounded in Tadeusz’s understanding of art based on the Enlightenment concept of modern art. He argues with a commonly accepted view that experimental art was persecuted in the Polish People’s Republic in the 1960s and the 1970s, and that the communist government showed any particular interest in fine art. In the annex, the author provides a full list of names found in Tadeusz’s files

Heat Transfer Through Plasma-Sprayed Thermal Barrier Coatings in Gas Turbines: A Review of Recent Work
No full textA review is presented of how heat transfer takes place in plasma-sprayed (zirconia-based) thermal barrier coatings (TBCs) during operation of gas turbines. These characteristics of TBCs are naturally of central importance to their function. Current state-of-the-art TBCs have relatively high levels of porosity (~15%) and the pore architecture (i.e., its morphology, connectivity, and scale) has a strong influence on the heat flow. Contributions from convective, conductive, and radiative heat transfer are considered, under a range of operating conditions, and the characteristics are illustrated with experimental data and modeling predictions. In fact, convective heat flow within TBCs usually makes a negligible contribution to the overall heat transfer through the coating, although what might be described as convection can be important if there are gross through-thickness defects such as segmentation cracks. Radiative heat transfer, on the other hand, can be significant within TBCs, depending on temperature and radiation scattering lengths, which in turn are sensitive to the grain structure and the pore architecture. Under most conditions of current interest, conductive heat transfer is largely predominant. However, it is not only conduction through solid ceramic that is important. Depending on the pore architecture, conduction through gas in the pores can play a significant role, particularly at the high gas pressures typically acting in gas turbines (although rarely applied in laboratory measurements of conductivity). The durability of the pore structure under service conditions is also of importance, and this review covers some recent work on how the pore architecture, and hence the conductivity, is affected by sintering phenomena. Some information is presented concerning the areas in which research and development work needs to be focussed if improvements in coating performance are to be achieved
