Abstract

In this paper, the performance of thermosyphon evacuated tube solar collector using TiO2/water has been numerically investigated using commercial software ANSYS. TiO2 nanoparticles were dispersed into the based fluid for volume fractions ranged ?=0.05-1%. The simulations were performed at three inclination angles of 30°, 45° and 60°. Numerical results indicated that the thermal performance of the evacuated tube was improved with nanofluids compared its base fluid. In addition, the thermal performance of the tube at inclination angle of 30° and 0.5vol.% was found to give the maximum enhancement which shows the highest thermosyphon and gravity effects on the evacuated tube.
