By means of reasonable assumption and mathematical derivation,a theoretic expression of flow rate for a single fracture with linearly varying width was obtained
<正>An analytical model is developed to study the surface effects on the vibration behavior including the natural frequency and the critical flow velocity of fl
Wing fapping and morphing can be very benefcial to managing the weight of micro air vehicles through coupling the aerodynamic forces with stability and control.
Electro-hydraulic servo valve is a typical complicated multi-domain system constituted by mechanical,electric,hydraulic and magnetic components,which is widely
