The Application of Local Search for Maximum Area to High Pressure Phase Equilibrium

Guo Jizhi,Liu Tao,Yuan Weikang

Strategic Study of CAE 2001, Volume 3, Issue 3,   Pages 56-60

Abstract:

The area method (AM) that minimizes the Gibbs energy by integrating, instead of differentiating, the Gibbs energy curve provides a sufficient condition for global Gibbs energy minimization rather than only a necessary condition provided by the flash equilibrium calculation method. However, it uses the method of exhaustion to search the positive maximum area, therefore requires a long calculation time. Here this method is modified as LSAM (local search area method), which is a repeated search shrinking vicinities of the liquid and gas equilibrium composition points located by previous rough search. The calculation time decreases to one over several thousands of AM’s or less. The experimental equilibrium data of benzene and propylene are used to demonstrate the merit of this method.

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 2,   Pages 219-223 doi: 10.1007/s11465-009-0024-y

Abstract: Based on structures and characteristics of traditional hydraulic pumps, this paper proposes a novel high-temperatureand high-pressure hydraulic pump (HHHP) that can work under 150°C and 28 MPa to overcome problems oftraditional high-temperature plunger pumps.The control signals of two cylinders are two separate triangle waveforms with 90° phase difference.Therefore, reduced fluctuations and stable pressure output is obtained.
