An Experimental Appraisal on the Efficacy of MWCNT-H2O Nanofluid on the Performance of Solar Parabolic Trough Collector

Harwinder Singh and Pushpendra Singh

An application of MWCNT nanoparticles and distilled water was used to prepare the nanofluid and this type of MWCNT based absorbing medium was found to be highly efficient in investigation of the performance of solar parabolic trough collector due to better thermo physical properties (i.e. thermal conductivity) acquired by the MWCNT based nanofluid. In present research study author decided to take volume concentration 0.01% and 0.02% and high quality surfactant Triton X-100 was used to enhance the dispersion quality of nanoparticles in conventional fluid. The test were performed under different volume flow rate conditions of nanofluid i.e. 160 L/h and 100 L/h. Experimental results show that with an incremental change in volume concentration from 0.01% to 0.02%, there is a substantial increment in efficiency of parabolic collector but observed only at 160 L/h.
