Based on the successful results of the Japanese national project for 300 kW ceramic gas turbine(CGT302) development (this project was finished in March 1999), the Ministry of International Trade and Industry (MITI) started “Research and Development on Practical Industrial Co-generation Technology” project in August 1999. The objective of this project is to encourage prompt industrial applications of co-generation technology that employs hybrid gas turbines (HGT; using both metal and ceramic parts in its high-temperature section) by confirming its soundness and reliability. The development activities are performed through material evaluation tests and long-term operation tests for the HGT of the medium size (8,000-kW class). It is expected that the development can realize low pollution and reducing the emission of CO2 with highly efficient use of energy. The HGT will be developed by applying ceramic components to an existing commercial 7,000-kW class gas turbine. The development targets are thermal efficiency of 34% or higher, output of 8,000-kW class, inlet temperature of 1250deg-C, and 4,000hrs of operation period for confirmation of reliability. The HGT for long-term evaluation tests and the test plant are under development. This paper gives the summary of last year’s developments in the HGT project.

This paper introduces the research and development of the temperature measurement system using wireless network based on ZigBee protocol. The system consists of network coordinator and a number of nodes. The structural and functional design for the nodes highlights the characteristics of industrial applications, and is of a certain reference value on research and development of industrial wireless sensor systems.

Scattered light sensors are optical sensors commonly used in industrial applications. They are particularly well suited to characterizing surface roughness. In contrast to most geometric measuring devices, a scattered light sensor measures reflection angles of surfaces according to the principle of the so-called mirror facet model. Surfaces can be evaluated based on the statistical distribution of the surface angles, meaning the gradients. To better understand how the sensor behaves, it is helpful to create a virtual model. Ray-tracing methods are just as conceivable as purely mathematical methods based on convolution. The mathematical description is especially interesting because it promotes fundamental comprehension of angle-resolved scattered light measurement technology and requires significantly less computation time than ray-tracing algorithms. Simplified and idealized assumptions are accepted. To reduce the effort required to simulate the sensor, an attempt was made to implement an idealized mathematical model using Matlab® to be able to quickly generate information on scattered light distribution without excessive effort. Studies were conducted to determine the extent to which the results of modeling correspond to the transfer characteristics of a virtual Zemax sensor, on the one hand, and with the measurement results of the actual scattered light sensor, on the other hand.

In recent years, a constantly growing interest in CFD accuracy assessment has been noticed in the open literature. In particular, this interest has grown considerably in the field of technical and industrial applications, since CFD is nowadays routinely used by many engineers, especially in research and development. In this paper, a contribution to this topic is presented. The most common issues about CFD uncertainty are reviewed and commented. Then, some findings originating from the application of three-dimensional numerical calculations to a model of the NASA Stage 37 axial compressor are reported. Particular attention is devoted to multistage turbomachinery modelling uncertainty in terms of rotor/stator interface models and rotor and stator gridding issues.

The purpose of this paper is to broadly assess the industrial applications of microwave power and to perhaps formulate some of the ingredients for a successful application. Traditional applications are reviewed and the ingredients for their success are noted. Also discussed will be a few applications that were not successful. Future uses of microwave power are hypothesized based upon research and development efforts in progress throughout industry.

Abstract The article describes chosen, yet key parts of newly established European, infrastructural research and development project ARIES (2017-2020) - Accelerator Research and Innovation for European Science and Society, to be realized inside the framework of the H2020 programme. Two institutions from Poland participate in ARIES – these are Warsaw University of Technology and Institute of Nuclear Chemistry and Technology. ARIES is a topical continuation of the previous infrastructural accelerator projects realized uninterruptedly since 2003 – FP6 CARE – Coordinated Accelerator Research in Europe and FP7 TIARA – Test Infrastructure and Accelerator Research Area, EuCARD – European Coordination for Accelerator Research and Development, and EuCARD2. The article is simultaneously a part of a series of papers concerning the participation of Polish doctoral students and young researchers, especially from the Warsaw University of Technology, in large European and world experiments of the discovery class, including building large research infrastructures like: FLASH and EXFEL, ESS, ITER and DEMO, IFMIF, but also satellites built by the ESA, etc. ARIES embraces, among others, the following subjects: energy efficiency and management, cost lowering, miniaturization and ultra-high field gradients, promotion innovation, industrial applications, societal implications, new materials and components, new methods of particles acceleration including laser-plasma-particles interaction, and building new generations of systems.
