PARABOLIC TROUGH SYSTEM OPERATING WITH NANOFLUIDS: COMAPARISON WITH THE CONVENTIONAL WORKING FLUIDS AND INFLUENCE ON THE SYSTEM PERFORMANCE

To analyse the behaviour of a parabolic trough operating with nanofluids, and compare its performance to the more traditional onesusing oil, a model for the thermal analysis of the system has been developed and implemented in Matlab. The simulations havebeen performed for a suspension of Al2O3 in synthetic oil and its characteristics compared to the corresponding basic liquid usedby itself. The string has been assumed to have a length of 100 m and a concentrating surface area of 550 m2. The simulations havebeen carried out for different DNI (Direct normal irradiance) and variable mass flow, ensuring a temperature at the collector outletbelow 400 °C. For a proper comparison, the following variables and efficiency indicators have been checked: power output,pumping power, thermal efficiency and overall efficiency of the parabolic trough system.
