In Chapter One, Fujun Wang, Chaoyue Wang, Zhengjun Yang, Peijian Zhou, and Zhifeng Yao propose and examine a dynamic mixed nonlinear SGS model, with the results indicating that this wall-resolved near-wall solution could capture details more accurately. In Chapter Two, Jos Gonzlez and Jess M. Fernndez present a study wherein the flow in a one stage, single volute centrifugal pump is examined at the Fluid Mechanics Laboratory at the Universidad de Oviedo. In Chapter Three, Hua-Shu Dou, Lulu Zheng, Zuchao Zhu, Xiaoping Chen, and Baoling Cui discuss the evolution of the separating flow and pressure variation distribution around the tongue region in a centrifugal pump. In Chapter Four, Angelo Leto discusses centrifugal pumps for liquid-propellant engines for space propulsion applications. Jamshid H. Karimov, MD, PhD, Shinji Okano, MD, and Kiyotaka Fukamachi, MD, PhD review continuous-flow mechanical circulatory support technology in Chapter Five. Next, Susanta K. Das wraps up the book with an experiment on the effect of impeller vane geometry design on the performance of a centrifugal pump.
