Abstract: A new type of solar-operated diffusion still is proposed. The still is powered directly by solar radiation and is easy to operate and maintain. Analyses of the proposed diffusion still and ...

Abstract: Mathematical modeling of a thin layer solar kiln for drying of agricultural products is presented. Governing equations of the air temperature and air humidity ratio, material temperature and its ...

Abstract: An optimal thermal design of a considered system configuration is conveniently decided when the system is modeled as made up of one thermodynamic subsystem and of the essential number of design ...

Abstract: Drill strings are used in oil and gas production as well as geothermal wells. They experience destructive vibrations, many of which are highly dependent on drill string modes. In this paper, ...

Abstract: Canadian municipalities spend $12–15 billion annually on infrastructure, but it does not seem to be enough. Similarly, it is reported in the United States that the cost of upgrading the water system would cost US $77 billion ...

Abstract: This is an attempt to establish a simple approach to nonequilibrium thermodynamics. A generalized entropy is formulated from an information theory viewpoint and from a thermodynamic viewpoint. ...

Abstract: This paper deals with the optimization of complex energy systems given a cost objective function. The optimization uses a decomposition strategy based on the second law of thermodynamics and a ...

Abstract: This paper deals with an application of the second-law-based optimization methodology described in Part 1 of this paper. The methodology is applied to a simple energy system of 10 components ...
