Thermodynamic analysis of a novel solar water heating system during low sun radiation in Iran

This paper reports a plenary thermodynamic model of a novel solar system for water heating in buildings. Energy and exergy analyses are used to characterize the exergy destruction rate in any component and calculate system overall efficiency. The system consists of a solar evaporator, a heat exchanger to produce hot water, and an auxiliary pump. A computer simulation program using EES software ...

Space Climate and the Solar-Stellar Connection: What can we Learn from the Stars about Long-Term Solar Variability

While it is well-known that solar variability influences the near-Earth Space environment at short timescales of days – an effect collectively termed as Space Weather, a more subtle influence of solar variability at longer timescales is also present and just beginning to be appreciated. Long-term solar forcing and its consequences – which has come to be known as Space Climate – has important co...

Early-Solar-System Radioactivity and AGB Stars

The possible stellar origin of those short-lived nuclei that were shown to be alive in the early solar system is briefly discussed. A possible revival of the model for a close-by AGB star polluting the protosolar nebula depends on the strongly debated problem of the initial amount of Fe, as inferred from recent measurements in early condensates.

Solar Latitudinal Distribution of Solar Flares around the Sun and Their Association with Forbush Decreases during the Period of 1986 to 2003

Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23. A statistical analysis was performed to obtain their relationship with sudden storm commencement (SSCs) and Forbush decrease events (Fd) of cosmic ray intensity. An 11-year cyclic variation ...
