Biography:
Dr Fatemeh Salehi is a Chief Investigator at Blue Economy Cooperative Research Center (CRC) and the Co-Deputy for Macquarie Sustainable Energy Centre. She received her PhD from the School of Photovoltaic and Renewable Energy Engineering in the University of New South Wales in 2015. She then worked as a postdoctoral research associate at the University of Sydney before joining Macquarie University in 2018. She is an expert in the field of computational modelling of multi-phase flows with emphasis on particle and droplet flows. "Multi-phase flows are common in a wide range of engineering applications from drug inhalers to fuel injectors in diesel engines and gas turbines. Despite this, significant gaps remain in our ability to predict such flows. The recent advance in high performance computational (HPC) capacities significantly increase the potential of the computational approaches to resolve the complex physics of such flows. Her research aims to develop predictive computational tools that form the basis for improving efficiency and creating new technologies which are better for our environment.”
Her research also involves developing novel combustion models. “Fossil fuels have the highest share in the worldwide used energy however combustion results in emissions of pollutants such as nitrogen oxides (NOx) and particulates which are harmful to human health and greenhouse gases such as carbon dioxide (CO2) which are associated with anthropogenic climate change. This research focuses on using mathematical/computational modelling to advance clean efficient energy technologies.” Dr Salehi has extensive experience in these fields and has worked with leading research laboratories in the USA, Germany, Italy, South Korea, China and Australia.
Dr Jafari joint the Centre for propulsion engineering at Cranfield University in December 2017 to focus on ultra high bypass ratio (UHBR) turbofan engines performance and optimization.
Before joining Cranfield, he was working with the Dynamic, Control, and Vehicle Research (DCVR) Group at the University of Sussex, where he spent three years working on an industry-linked project with Ford, Ricardo, and Denso. The project involved the design, modelling, control, and optimisation of advanced thermal management systems for internal combustion engines.
Prior to that, he was an assistant professor in the Department of Aerospace Engineering at Sharif University of Technology from 2013 to 2015. Alongside his teaching activities his research focused on the control and multidisciplinary design optimisation of gas turbine engines. Soheil gained his PhD at the Iran University of Science and Technology in 2011. His work resulted in the first national electronic control unit (ECU) for aeroengines in Iran.
Summary:
Fossil fuels are still the main source for energy generation in spite of their harmful impact on the environment and our health. They particularly result in particle pollution which is now the world’s largest single environmental health risk as it causes around 7 million deaths per year (1 in 8 global deaths). Exposure to particulate matter pollutants results in serious health issues such as significant cardiopulmonary risk in adults, lung cancer, increased all-cause mortality, and long-term respiratory decline in children. Hence, developing cost-effective low-emission energy technologies is now one of the hottest research areas. Due to the rapid growth of available computational resources, computational fluid dynamic (CFD) techniques have become effective tools to address increasingly complex problems. This talk focuses on the use of advanced computational modelling approaches to develop clean, safe and efficient energy technologies. Dr Salehi will discuss the challenges on modelling turbulence-chemistry interactions to address the formation of toxic pollutant. This will be followed by the use of CFD models for the production of bio-oil from biomass.
