Abstract: This paper presents the exergy balance equation on a solar collector which acts as the fundamental and principal expression for the solar thermal design. The equation fully explains the exergy ...

Abstract: An oil hammer generates a greater pressure than that supplied to a pipeline, and sometimes causes equipment breakdown. The author intends to actively utilize this pressure rise. A new type of ...

Abstract: In a previous paper the author proposed to actively utilize the pressure rise phenomenon of an oil hammer and a new type of a hydraulic pressure intensifier using oil hammers. In this paper, ...

Abstract: The theoretical analysis and optimization of two different types of solar collectors connected in series are presented. The energetical approach to the cascade system with two types of collectors ...

Abstract: To achieve high recording density, the combination of low flying head and smooth disk surface is very desirable. Although high stiction associated with the smooth surface can be avoided by ...

Abstract: AbstractThis study explores the effects of black carbon (BC) and sulfate (SO4) on global and tropical precipitation with a climate model. Results show that BC causes a decrease in global annual mean precipitation, consisting ...

Abstract: This study deals with an experimental investigation of a cylindrical roller bearing having annular rollers. Comparisons are made with a solid roller bearing having the same configuration and ...

Abstract: Theoretical and experimental study on dynamic behavior of submarine pipelines under laying operation with articulated stingers is described in this paper. Wave response tests in regular waves and ...

Abstract: Optical cascade heat collection of solar energy has proved effective for gaining thermal energy in the medium temperature region (80∼150° C). The cascade system consists of two separate ...
