The growing need for sustainable energy solutions has driven research into co-combustion processes, where coal is blended with biomass to reduce emissions and enhance combustion efficiency. This book overviews best practices to optimise the combustion processes through the use of computational fluid dynamics (CFD) simulations, focusing particularly on solid fuel combustion modelling. It equips the reader with an understanding of combustion parameter optimisation and modelling from a thermodynamic-fluid dynamic-mass transfer perspective.
Key features
- Offers a specialised approach to solid fuel co-combustion, using CFD to model and optimise combustion processes for sustainable energy solutions
- Combines theoretical and practical applications, with a focus on energy optimisation and emissions reduction
- Includes modelling of complex phenomena such as multiphase and reaction modelling
- Gives insights into important sub-models required during combustion modelling, forming the basis of reliable models

Innocent Musonda is a registered civil engineer and professional construction manager, currently serving as a full professor in Construction Management and Quantity Surveying in the Department of Construction & Management-Quantity Surveying at the University of Johannesburg (UJ). He is also the director of the Centre for Applied Research and Innovation in the Built Environment (CARINBE). He has taught a broad spectrum of courses in construction project management, engineering management, and digital built-environment technologies. As an experienced academic and practitioner, he combines more than two decades of industrial experience across Botswana, Zambia, and South Africa with deep scholarly engagement. Prof Musonda is particularly passionate about advancing engineering design for sustainable, safe, and digitally enabled infrastructure. His expertise spans building information modelling (BIM), digital twins, digital transformation in the built environment, sustainable infrastructure, and construction of health and safety. He has made substantial contributions to both academia and practice, serving as a thought leader in digitalisation and transformation in infrastructure. His applied work addresses societal and industry challenges, including infrastructure safety, sustainability, and the integration of 4IR technologies in construction. On the research side, Prof Musonda has published extensively and supervised numerous postgraduate students. At his inauguration, it was noted that he has supervised 8 PhD students and over 20 master's students, and has authored more than 60 journal articles, 4 book chapters, and over 50 conference papers. He is rated by the National Research Foundation (NRF) in South Africa (C2). His work is strongly aligned with the UN's Sustainable Development Goals, particularly around sustainable infrastructure and digital innovation. Beyond research and teaching, Prof Musonda is deeply engaged with professional bodies. He is a full member of the Chartered Institute of Building (CIOB-UK) and the International Council for Research and Innovation in Building and Construction (CIB). He also contributes to national and international peer review processes, acting as an assessor for bodies such as the Australian Research Council (ARC) and the NRF. He has chaired and co-edited influential conferences, most notably the Development and Investments in Infrastructure (DII) series, helping drive discourse on infrastructure development, sustainability, and investment across Africa. Prof Musonda is a very hard-working scholar-practitioner, committed to bridging the gap between academic research and real-world infrastructure transformation. His leadership at CARINBE helps make his academic work industry-relevant, and his mentorship of students drives capacity-building in the built environment in Africa.
