Simulation Tools and Methods for Supercritical Carbon Dioxide Radial Inflow Turbine: Development and Application on Open-Source Code

China has set a goal to peak carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060, which promotes the use and development of renewable energy. This book introduces simulation tools and methods for supercritical CO2 radial inflow turbines, including a high-fidelity quasi-one-dimensional design procedure, a non-ideal compressible fluid dynamics Riemann solver, and a multi-objective Nelder–Mead geometry optimizer. It also presents enhanced one-dimensional loss models to predict the performance of the turbine.

China has taken significant steps towards protecting the Earth by setting ambitious targets for reducing carbon dioxide emissions. The country aims to peak carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060, which strongly promotes the development and utilization of renewable energy sources.

One promising technology for generating electricity from renewable energy sources is the supercritical CO2 power cycle. However, designing and optimizing the radial inflow turbine, which is a crucial component of this cycle, poses significant challenges. This book aims to address these challenges by introducing simulation tools and methods for supercritical CO2 radial inflow turbines.

The book includes a high-fidelity quasi-one-dimensional design procedure, a non-ideal compressible fluid dynamics Riemann solver within the open-source CFD software OpenFOAM framework, and a multi-objective Nelder–Mead geometry optimizer. Enhanced one-dimensional loss models are presented to provide insights into the preliminary design of the supercritical CO2 radial inflow turbine.

Since the flow phenomena within the blade channels of the turbine are complex, involving fluid flow, shock wave transmission, and boundary layer separation, employing the ideal gas model alone is insufficient to predict the turbine's performance accurately. Therefore, a non-ideal compressible fluid dynamics Riemann solver based on the OpenFOAM library is developed.

This book addresses the issues related to turbine design and blade optimization and provides leading techniques. It is of great value to readers working on supercritical CO2 radial inflow turbines and those seeking to understand the knowledge of CFD and turbomachinery.
