CFD Analysis and Experimental Investigation on Thermal Performance of Closed loop Pulsating Heat pipe using different Nanofluids
Abstract: This paper presents Enhancement of the Thermal performance of a heat pipe charged with Nanofluids. The SiO2 /DI Water and Al2O3/DI Water served as the working nanofluids with concentrations by different mass 10g/lit, 20g/lit, 30g/lit in heat pipe. The heat pipe is fabricated by a straight copper tube with an outer diameter 3mm, thicknes 1mm and length of 1785mm. This paper presents a discussion on the effect of various performing parameters by varying different heat inputs as well as nanofluids concentration as SiO2/DI Water and Al2O3/DI Water. CFD results analysis to comparison for Experimental results show that at a heating power of 10w, 14w, 18w, 22w the Thermal resistance, Thermal heat transfer Co-efficient, Thermal Thermal conductivity and Efficiency for CLPHP SiO2/DI Water and Al2O3/DI Water heat pipe are 69.37%, 75.99% and 11.98% DI water respectively, which are better than that of pipes using DI water as the working na-nofluids.
