Abstract
Nanoparticles have been thoroughly investigated in the last few decades because they have many beneficial and functional qualities. Their capability to enhance and manipulate light absorption, thermal conductivity, and heat transfer efficiency has attracted significant research attention. This systematic and comprehensive work is a critical review of research on the photothermal energy conversion performance of various nanofluids as well as the recent advances in several engineering applications. Different nanofluids used in the photothermal energy conversion process were compared to identify the suitable applications of each nanofluid in thermal systems. An analysis of the previous investigations based on experimental and numerical studies has established that nanomaterials have the potential to increase the efficiency of solar thermal systems.
Highlights
In the last century, global industrialization has led human civilization to several beneficial ideas, such as infrastructure that connects countries, continents, or even planets and energy harvesting technologies that can be used to collect energy in various forms
Numerous studies have shown that the efficiency of the solar thermal collector can be increased when various nanofluids are used as the working fluid
The thermal and overall efficiency of the various solar thermal collectors depend on the type of nanofluid and the properties of
Summary
Global industrialization has led human civilization to several beneficial ideas, such as infrastructure that connects countries, continents, or even planets and energy harvesting technologies that can be used to collect energy in various forms. Such industrialization has led to catastrophic events, natural resource depletion, sea-level rise, and global warming. It affects wildlife in forests worldwide, causing contagious diseases and epidemics. Protocol [1], which was implemented to decrease the acceleration of global warming by significantly reducing the emission of greenhouse gases such as methane (CH4 ), carbon dioxide (CO2 ), nitrous oxide (N2 O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and sulfur hexafluoride (SF6 ).
