M. Stachowicz, J. Mażulis, K. Granat, A. Janus, Wroclaw University of Technology,Department of Foundry Engineering and Automation, Wrocław, Poland The paper presents the results of applying microwaves to support the drying, redrying and hardening process of molding and core sands made of different types of matrix. In the tests of the microwave heating process a slot line measuring stand was use...

Aiming at simulating air-heating systems, two algorithms were developed for the calculation of finned elliptical-tube heat exchangers, whose basic difference lies in the kind of hot fluid employed: saturated steam or hot liquid. In both cases, a crossflow unit, in which the cold fluid is mixed and always flows on the shell side, is considered. The hot fluid may exhibit multiple passes in the tu...

Intermittent microwave drying improves the quality of dehydrated product, because reduces effect hot spots. Mathematical modelling is essential to understand physics this process and optimize operation conditions. However, there are few studies about intermittent drying. This work proposed a mathematical model based on mass balances liquid vapor water in which non-equilibrium formulation descri...

Long wave radiation (LWR) forcing is determined in atmospheric global climate models (AGCMs) by a heating algorithm embedded in the model. These algorithms compute vertical heating rate (HR) profiles from profiles of temperature (T), moisture (Q), clouds, and minor atmospheric constituents; thus the HRs depend on the vertical structure of the input variables plus internal physics. The sensitivi...

Detailed profiles of nuclear heating and radiation damage parameters were determined in ITER blanket modules at different poloidal locations. The results indicate that the nuclear parameters are sensitive to the configuration and material composition with enhanced steel heating and helium production in regions with large water content.

Microwave is the machine, which is very helpful for the food sector. The modern age of life as well as the increasing number of working women requires simplified routines and standardization of foods with lesser preparation time and convenience in usage. The demands of the consumers are the real factor for the success or failure of any food items in the present scenario. The increasing consumer...

A novel measurement technique, based on infrared thermography, has been applied for characterizing the thermal properties of paper with high spatial resolution. The technique is termed as ‘active thermography’ since the temperature response of a paper sheet is observed and analyzed with respect to an external periodic heating. Through the analysis of the temperature response of the paper surfac...

A number of heating sources are available for minimally invasive thermal therapy of tumours. The purpose of this work was to compare, theoretically, the heating characteristics of interstitial microwave, laser and ultrasound sources in three tissue sites: breast, brain and liver. Using a numerical method, the heating patterns, temperature profiles and expected volumes of thermal damage were cal...

AIMS To study the influence of culture preservation methods and culture conditions on the production of the mycotoxins patulin and citrinin by Penicillium expansum. METHODS AND RESULTS Ten strains of Penicillium expansum were preserved using subculture and maintenance at 4 degrees C, mineral oil, drying on silica gel and freeze-drying. Patulin and citrinin production was assessed on yeast ext...
