In the present paper a new multi-objective optimisation procedure for design of shell-and-tube Latent Heat Thermal Energy Storage (LHTES) is proposed. A simple arrangement cylindrical shell with multiple vertical tubes has been examined. The considers, as variables, number tubes, tube internal radius and device height-to-diameter ratio, H/D, while storage volume kept constant. This analysis aim...

In this research, a numerical analysis is accomplished aiming to investigate the effects of adding new design fins arrangement vertical triplex tube latent heat storage system during melting mechanism and evaluate natural convection effect using Ansys Fluent software. tube, phase change material (PCM) included in middle while transfer fluid (HTF) flows through interior exterior pipes. The propo...

Jatropha curcas belongs to family of Euphorbiaceae, and is an important biological tree species for diesel production. The current descriptions of the phenotypic traits for male and female flowers are not comprehensive and there have been no reports about the process of J. curcas from pollen germination on stigma to pollen tubes conducting fertilization after entering the ovary and ovule. To as...

Sir, I read the detailed description given by Lund et al.1 with great interest. Two years ago, while studying very preterm babies, I began to use an almost identical system. Since then I have made several modifications which have increased its versatility, simplified the changing of the slings, and greatly improved its acceptability for use with very small and immature subjects (Figure). As our...
