Paper Title
Atechnical Review of Nanofluids-Based Parabolic Trough Solar Collector (NPTSC)

Abstract
Abstract - Increasing electricity demand in the global energy profile, as well as a desire to reduce carbon emissions, encourage governments to use renewable energy sources such as solar. This paper represents an extensive review study on experimental and numerical work done on parabolic trough solar collectors (PTSC) using nanofluid. Nanofluid has great potential to enhance the thermal efficiency of the solar collector. As a result, it's no surprise that using nanofluids in solar collectors has become a major research topic. But still there are many obstacles in using of nanofluid as it has stability issues at higher temperature in most cases, environmental effects, producing it in large-scale for industrial use and its disposal is also difficult process. In this paper, literature review has done on the recent advancements in solar trough using nanofluid is studied and the comparison between their performances and efficiencies is also noted. The main research gaps and further areas for research are suggested in it Keywords - Parabolic trough collector, Nanofluid, thermal efficiency, MCRT
