Field Experiment of Solar Thermosyphon

Parametric Quantification of Low GWP Refrigerant for Thermosyphon Driven Solar Water Heating System

Modern lifestyle, industrialization and economy thrive on energy which is getting expensive overtime. Thermosyphon based systems are getting attraction for their promising heat transfer efficiency and zero energy utilization. Refrigerants having ozone depletion potential (ODP) and high Global Warming Potential (GWP) have been banned or under time bared permission under Montreal (1987) and Kyoto...

Promotion the efficiency of thermosyphon solar-electrical water heater using daily scheduled timer key

The solar radiation energy is one of the clean, essential and renewable resources for future. Iran, having 300 annual sunny days, has such intrinsic potential and thermosyphon solar-electrical water heaters (TSEWH) are the simplest solar-thermal convertors. Despite their unique merits, they can not supply hot water for domestic applications during cold period, so, an auxiliary backup system suc...

Reconstruction of Solar Coronal Linear Force-Free Magnetic Field

Status of the BOREXINO Solar Neutrino Experiment

Aim of BOREXINO is to measure in real time low energetic solar neutrinos via neutrino electron scattering. Special interest in BOREXINO is the measurement of the counting rate of the 861 keV 7 Be solar neutrinos in order to separate between scenarios beyond the standard model which are favored by the results of running solar neutrino experiments. The solar neutrino puzzle originates from the di...

The effect of magnetic field and nanofluid on thermal performance of two-phase closed thermosyphon (TPCT)

The efficiency of two-phase closed thermosyphon (TPCT) with nanofluid as working fluid under magnetic field effect was investigated experimentally. In this study, silver/water nanofluid with different concentration (20 to 80ppm) is tested. Also, magnetic field with various strength (0.12, 0.35 and 1.2 T) exerted to TPCT by permanent magnet. It was seen that the TPCT heat transfer performance an...
