In this paper, a general procedure is presented which permits the units to be described by both distributed and lumped parameter models. The partial differential equations resulting from a distributed parameter model are transformed into a set of ordinary differential equations by discretizing the ...
1.On the basis of the constituents and energy conservation and with an electrochemical model being taken into account,a simulation model of the fuel cell in question was established based on the distributed-lumped parameter technology and modularization concept.在组分和能量守恒的基础上,考虑了电化学模...
The Distributed Parameters Line block implements an N-phase distributed parameter line model with lumped losses. The model is based on the Bergeron's traveling wave method used by the Electromagnetic Transient Program (EMTP) [1]. In this model, the lossless distributed LC line is characterized by...

(2000) used the same lumped parameter model, and related it to a particular model of head vibrations. The helmet component deformations or strains are shown as a function of time in Figure 16.10, for an impact of a flat striker on a region of the shell with a 140 mm mean radius of ...

To optimize the design, the size of the diffuser throat in the micropump was varied and used as a design parameter. The optimization results indicate that there exists an optimal width for the diffuser throat, which is critically important to the design of an ejector driven micropump. For ...
In this paper, sufficient conditions for stability and complete stability of equilibrium of a mixed distributed and lumped parameter feed-back control system are established. The system is in the form of a parabolic partial differential equation coupled with a set of first-order non-linear ordinary...
