Speech Title: Environmental impacts of using nanofluids in Renewable Energy Systems


It has been more than two decades since the discovery of ‘nanofluids’ – mixtures of common liquids and solid nanoparticles with at least one dimension below 100 nm in size. While colloidal suspensions of particles (which include larger particles) have been studied for several decades, the term ‘nanofluids’ designates fluid systems that have enhanced thermal and optical properties. Although barriers to their commercial adoption remain, the field of nanofluids has continued to grow. Many studies have considered the effects of adding nanoparticles on the thermal efficiency and exergy efficiency of renewable energy systems particularly solar systems, however, few have investigated their potential for emission reductions. Critically, since renewable energy technologies aim to reduce the environmental impact of energy systems, this talk focuses on whether nanofluids provide a net environmental benefit. Thus, in addition to providing a comprehensive overview of this body of literature from an environmental perspective, this talk also highlights areas for future work that could help ensure that nanofluids have a net positive environmental impact in renewable energy systems going forward.


In recent years, Professor Omid Mahian research directions have mainly included the application of nanotechnology in renewable energy (such as the application of nanofluids in solar collectors and solar seawater desalination) and the use of entropy generation and (exhaust) analysis in energy systems. application. So far, He is editor in several prestigious journals such as Renewable Energy ( Elsevier), Energy (Elsevier) and Journal of Thermal Analysis and Calorimetry (Springer) and he has published more than 150 SCI papers, which have been cited more than 10,000 times.
