Abstract

Thermosiphon is based on natural convection in which the flow is driven by a thermally generated density gradient without any use of a mechanical pump through passive heat exchange method. A two-dimensional rectangular Thermosiphon(32mm*400mm) which has three sections namely, condenser, adiabatic, evaporator with four different water levels i.e., at 26mm, 52mm, 104mm, 120mm are considered. Since it is wickless model, gravitational force will act on it. The objective of the work is to investigate the heat transfer performance of Thermosiphon using pure water and Nano fluids namely, Al2O3-water, SiC-water at different volumetric fractions i.e., 1%, 2% and 3%, using fluent software, multiphase mixture model. The Thermosiphon performance is investigated in terms of temperature profile, volume fraction of gas, volume fraction of water and Nusselt number. The finaloutcome revealed that Sic-water Nano fluid with 3% volumetric fraction has shown better heat transfer augmentation compared to Al2O3-water and pure water.
