coefficient. α and M are material parameters which describe the relative compressibility of the constituents. fi and γ denote the body force and the rate of fluid injection into the media, respectively. Equations (1) and (2) with the aid of Eqs. (3) and (4) in the absence of body force and the rate of fluid injection into the media can be reduced to ......

J. Cent. South Univ. (2012) 19: 2627-2633 DOI: 10.1007/s11771-012-1320-y Fluid inclusion characteristics of Longmenshan copper-polymetallic deposit in Yueshan, Anhui Province, China LIU Zhong... conditions of primary fluid inclusions were researched. The results show that the primary fluid inclusions contain vapor and liquid phase type (Type I), daughter mineral-bearing type (Type II) and pure......
-magnetic, mechanical and fluid subsystems of the valve were investigated, including their interactions. Governing equations of the valve were derived in the form of nonlinear state equations. By comparing the simulated and measured data, the simulation model is validated with a deviation less than 15%, which can be used for the structural design and control algorithm optimization of proportional......
