Подготовка специалистов паро- и газотурбинистов в Киевском политехническом институте (конец XIX–XX вв.)

В статье рассказывается про историю подготовки в Киевском политехническом институте специалистов по паровым и газовым турбинам (конец ХІХ–ХХ вв.): подготовку инженерных и научно-педагогических кадров, научно-исследовательские работы, сотрудничество с научно-исследовательскими институтами и турбостроительными заводами СССР, создание головных образцов мощных теплофикационных паровых турбин и газотурбинных установок, которые использовались для развития энергетики.In this article the history of preparation of specialists in area of steam- and gas-turbines in the Kyiv Polytechnic Institute (end of XIX–XX centuries) is presented. The training of engineerings and scientific-pedagogical personnels, research works, collaboration with scientific-research institutes and turbine manufacture factories of the USSR, creation of brassboards of powerful introduction of a heating system steam-turbines and gas-turbine settings which were used for development of a power generation, had been described in it

An improved design of spark-protected microstrip gas counters (R-MSGC)

We have developed microstrip gas counters manufactured on standard printed circuit board and having the following features: resistive cathode strips, thin (10 micron) metallic anode strips and electrodes protected against surface discharges by a Coverlay layer at their edges. These features allow the detector to operate at gas gains as high as can be achieve with the best microstrip gas counters manufactured on glass substrates. We believe that after further developments this type of detectors can compete in some applications with other micropattern detectors, for example MICROMEGAS.Comment: Presented at the 7th RD51 Collaboration meeting, CERN, April 201

Hardness, grainsize and porosity formation prediction on the Laser Metal Deposition of AISI 304 stainless steel

The presented numerical model solves the heat and mass transfer equations in the Laser Metal Deposition process and based on the evolution of the thermal field predicts the grainsize, the resulting hardness and evaluates the pores formation probability in an AISI 304 stainless steel. For this purpose, in a first step, the model calculates the shape of the deposited material and the variations of the temperature field. In a second step, and based on the evolution of the thermal field, the model calculates the resulting hardness of the deposited material, the grainsize and the porosity formation probability after the deposition process. Numerical results are experimentally validated, and good agreement is obtained. Consequently, besides predicting the geometry of the resulting part and the evolution of the thermal field, the developed model enables to evaluate the quality of the deposited material. Therefore, the optimum process conditions and strategy when depositing AISI 304 stainless steel can be determined without initial trial-and-error tests.“LaCaixa” foundation .

CCS from industrial sources

The literature concerning the application of CCS to industry is reviewed. Costs are presented for different sectors including ``high purity'' (processes which inherently produce a high concentration of CO2), cement, iron and steel, refinery and biomass. The application of CCS to industry is a field which has had much less attention than its application to the electricity production sector. Costs range from less than $2011 10/tCO 2 up to above$ 2011 100/tCO 2 . In the words of a synthesis report from the United Nations Industrial Development Organisation (UNIDO) ``This area has so far not been the focus of discussions and therefore much attention needs to be paid to the application of CCS to industrial sources if the full potential of CCS is to be unlocked''
