The issue of mechanical energy budget has received a lot of attention in open-channel flows which are frequently turbulent. Turbulent motions play a major role in the total mechanical energy of the flow field. It is difficult to evaluate total mechan

The system \begin{equation*} \ddot{q}_k+\gamma \dot{q}_k=V'(q_{k+1}-q_k)-V'(q_k-q_{k-1})\qquad (k=1,\ldots,N-2) \end{equation*} is considered, where $00$ (fixed endpoints – this is the original Fermi–Pasta–Ulam oscillator provided that the damp

Flow instability in a miniature centrifugal pump is numerically simulated with the RANS equations and the SST k-ω turbulence model. The energy gradient method is adopted to analyze the flow instability at design load and two off-design loads, and th

Introduction: Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is a rapidly applicable type of mechanical circulatory support that overcomes acute hemodynamic breakdowns, whether in acute or chronic heart failure or cardiac arrest. In rece

To more fully immerse users in virtual environments, the use of a natural walking locomotion interface has been shown to be superior in simulating natural feelings. In such systems, simulating sloped areas is more difficult than level ground. In the
