Numerical Investigation of Direct Absorption Solar Collector using Nanofluids: A Review

摘要

Research on direct absorption solar collector(DASC)has been quite mtensive in the past decade.Solar thermal collector plays a vital role to determine the perfomance of DASC by utilized the heat transfer fluid to harvest the energy while the use of nanofluid(nanoparticle dispersion in a base fluid)enhanced the thermal conductivity.A lot of researchers have studied the influence of several parameters such as collector geometry and nanoparticle materials on the solar thermal collector efficiency for the past decade.This paper presents a recent progress on numerical modelling of nanofluid direct absorption solar collector(NDASC)for different type of geometry including flat type,parabolic trough and cylindrical tube.In this review,a more comprehensive numerical methods and solar collector geometry on NDASC are summarized.Finally,some recommendations are presented for future research guidance.
