Kinematic Model for a Far Infrared Vacuum Dryer

Abstract

Energy analyses in drying of welsh onion from one source of far infrared radiation at an absolute pressure of 2.6 and 5 kPa were carried out to determine the energy input at which the highest level of efficiency would be attained. The experimental results were used not only to formulate an advanced mathematical model for the prediction of moisture content of onion as a function of drying time but also to study the dryer efficiencies. Less than half of energy input was utilized for evaporating water from the onion. Approximately 73–99% of operating efficiency, which was dependent on the dryer configuration, was converted into radiant energy. The highest radiant efficiency was obtained at 40 W initial power supply, which was equivalent to the source temperature of about 100°C. An 80 W initial electrical power supply at a 10 cm distance of heater from the onion surface showed the highest drying efficiencies. At 80 W power, efficiency decreased with increasing distance from the heater source but at the expense of quality. For optimum drying efficiency without compromising quality, distance of heater from onion surface was proposed to be 10 cm.

Energy and exergy analyses of electrolytic hydrogen production with molybdenum-oxo catalysts

This paper analyzes a new low-temperature electrolysis hydrogen production system using molybdenum-oxo catalysts in the cathode and a platinum based anode. A thermodynamic model is developed for the electrolysis process in order to predict and analyze the energy and exergy efficiencies. The new electrolysis system with molybdenum-oxo catalysts consists of two half cells of PEM (proton exchange membrane) and alkaline electrolysis. The effects of temperature and membrane thickness are reported at varying current densities. The results are presented and compared with previous studies to demonstrate the promising performance of the system.

On institutions for modular coalgebraic specifications

We present an algebraic extension of standard coalgebraic specification techniques for state-based systems which allows us to integrate constants and n-ary operations in a smooth way and which leads to institutions enabling the use of modular specification techniques. A sound and complete proof system for first-order observational properties of modular specifications is given. The framework of (Ω,Ξ)-structures that we present can be considered as the result of a transformation of concepts of observational logic as in Hennicker and Bidoit (in: A. Haeberer (Ed.), Algebraic Methodology and Software Technology (AMAST’98), Lecture Notes in Computer Science, vol. 1548, Springer, Berlin, 1999) into the coalgebraic world. Moreover, it is shown that the features of (Ω,Ξ)-structures that make them suitable models for an observational approach to specifications can be categorically expressed by the fact that the operation mapping an (Ω,Ξ)-structure to its behaviour is a fibred idempotent monad.
