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.

The Microwave oven is a system used to convert the electromagnetic energy to thermal energy when the microwave cavity is loaded with a dielectric material. The ordinary microwave ovens are not supported with complex features for detecting parameters such as temperature, weight, and loaded material availability. Due to the lack of material availability, several laboratory and industrial applications require these features to switch off the oven. The reflections of electromagnetic radiation inside an empty microwave oven lead to oven damage. An overview of the microwave oven characteristics and emergence of electromagnetic radiation inside a microwave oven is presented in this study. The parameters measured inside the microwave oven, methods for power attenuation in a microwave oven, microwave power detector, and microwave oven leakage are discussed as well. Moreover in the methodology of this work, proposed a new technique based on the measurement of leaked microwave power to control the microwave oven. The preliminary results showed that the leakage measurement of electromagnetic power changes with the state/phase of the material inside the microwave oven, which ensured the possibility of the proposed promising technique. This work will be continued to connect the microwave oven with a spectrum analyzer and computer via hardware and software interfaces depending on the methodology of this article. A computer code will be developed to read the measured power and automatically switch off the microwave oven depending on materials state. Index Terms— Microwave, power, measurement, control.

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.

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.

Rehydration Process

It is very important to develop a new way of treatment for foodstuffs to provide consumers more chances to choose their foods. In the present study, we aimed to investigate the effect of microwave drying conditions on the rehydration process of Algerian truffles. Previously dried truffles, at different microwave power output (350, 500 and 650 Watt) and weights (100 and 150 g) have been utilized to analyses and to model the rehydration kinetics. Among the six used empirical models, Weibull model has been the most fitted model to all the treated samples. Microwave power output and sample weight were found to have an effect on truffles during drying, and consequently on their rehydration capacity. The high samples amount has decreased the effects of microwave drying by decreasing the density of treatment, also, the high-power output has probably reduced the time of evaporation, and thus more preservation to the dried truffles. These results can be taken into consideration for more industrial applications of microwave drying and subsequent rehydration of truffles.

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.
