Computational Fluid Dynamics (CFD) has been firmly established as a fundamental
discipline to advancing research on energy engineering. The major progresses achieved during the
last two decades both on software modelling capabilities and hardware computing power have
resulted in considerable and widespread CFD interest among scientist and engineers. Numerical
modelling and simulation developments are increasingly contributing to the current state of the art in
many energy engineering aspects, such as power generation, combustion, wind energy, concentrated
solar power, hydro power, gas and steam turbines, fuel cells, and many others. This review intends to
provide an overview of the CFD applications in energy and thermal engineering, as a presentation and
background for the Special Issue “CFD Applications in Energy Engineering Research and Simulation”
published by Processes in 2020. A brief introduction to the most significant reviews that have been
published on the particular topics is provided. The objective is to provide an overview of the CFD
applications in energy and thermal engineering, highlighting the review papers published on the
different topics, so that readers can refer to the different review papers for a thorough revision of the
state of the art and contributions into the particular field of interest
