Two-phase Closed Thermosyphon with Nanofluids
Nanofluids, stabilized suspensions of nanoparticles typically < 100 nm in conventional fluids, are evolving as potential enhanced heat transfer fluids due to their better thermal conductivity, increase in single phase heat transfer coefficient and significant increase in critical boiling heat flux. In the present paper, we investigate the overall thermal resistance of a closed two-phase thermos...
متن کاملExperimental Investigation of Boiling and Condensation Heat Transfer of a two Phase Closed Thermosyphon
In this paper the heat transfer characteristics of a two-phase closed thermosyphon over a wide range of heat transfer rates, system pressure, aspect ratios and filling ratios were studied. The experiments focused on the boiling and condensation heat transfer characteristics of the thermosyphon. The experimental boiling and condensation heat transfer coefficients inside the thermosyphon were com...
متن کاملExperimental Investigation of Boiling and Condensation Heat Transfer of a Two Phase Closed Thermosyphon
In this paper the heat transfer characteristics of a two-phase closed thermosyphon over a wide range of heat transfer rates, system pressure, aspect ratios and filling ratios were studied. The experiments focused on the boiling and condensation heat transfer characteristics of a thermosyphon with a copper tube having 25 and 32 mm inside and outside diameters. Distilled water was used as the wor...
متن کاملNumerical Analysis of the Effect of Filling Ratio on the Transient Behaviour of a Two-Phase Closed Thermosyphon
The use of the two-phase closed thermosyphons (TPCTs) is increasing for many heat transfer applications. In this study, the development of a numerical model is presented with the purpose of determining the transient characteristics of a TPCT. The model includes the heat transfer through the wall, vapour core, liquid pool and the falling condensate film. The complete two-dimensional conservation...
متن کاملThe 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...
