Experimental Investigation of an Al2O3 / Distilled Water Nanofluid Used In the Heat Pipes of Heat Exchangers
Abstract
This study investigates
the thermal performance of a heat pipe heat recovery system in air-to-air heat
recovery systems using a nanofluid of Al2O3 (aluminum
oxide) particles and distilled water. The experimental setup used 15 wickless vacuumed
copper pipes with a length of 1000 mm, a 10.5 mm inner diameter and a 12 mm
outer diameter. The evaporator section consists of 450 mm of heat pipes, the
condenser section is 400 mm, and the adiabatic section is 150 mm. In
experimental studies, 33% of the evaporator volume of the heat pipes was filled
with working fluids. Experiments were carried out at temperatures between 25ºC and 90ºC by using five
different cooling air flows (40 g/s, 42 g/s, 45 g/s, 61 g/s and 84 g/s), and
two different heating powers (3 kW and 6 kW) for the evaporation section, to
determine the heat removed from the condensation section. Experiments were
performed for distilled water and Al2O3 nanofluid,
respectively, and the results were compared with each other. As a result of the
experiments, it was observed that using a nanofluid as the working fluid
increased the efficiency of the heat pipe. The highest efficiency (η
= 59%) was
obtained in the experiments carried out using an Al2O3 nanofluid at a heating power of 3 kW and an air
flow of 112 g/s.
