In this paper the steady state performance of a variable conductance heat pipe, which its working fluid consists of two components (R11+ R113) is modeled. The role of the liquid film momentum and axial normal stresses are considered by use of the mean property of mixture and the governing equations are solved by conventional numerical methods. The results of the present model have been compared...

in this study. optimum allocation of heat transfer inventory for heat exchangers in a refrigeration system with specified power input or cooling capacity. and for a heat pump with specified heating capacity is investigated. the ratio of hot- to cold-end conductance unit cost ratio. g.was considered in the analysis as an additional variable of considerable importance to the designer summarized e...

A mechanism for the validity of a local version of the fluctuation theorem, uniform in the system size, is discussed for a reversible chain of weakly coupled Anosov systems.

Non-linear diffusion or Variable Conductance Diffusion (VCD) processes can be used as to filter away noise while preserving boundary information. However, adjustment of the control parameters is not well understood. By approaching the control of VCD systems through a multiscale statistical analysis, information about the image is revealed regarding the strength of boundaries and their influence...

Of concern is a network in which the conductance of certain branches are variable. The problem posed is the maximization of the joint conductance subject to a bound on the <t norm of the variable conductances. It is shown that at P an optimum state the conductance of a variable branch is proportional to the 2/(p+l) power of the current through the branch. l*his relation together with a dual var...

A computational model was developed to evaluate the influence of the calcium-dependent potassium conductance (gKCa), the calcium concentration in soma (varying the velocity of calcium extrusion velext and the calcium conductances in soma – gCaN and gCaP), the inclusion of a slow inactivation state variable in soma's fast sodium conductance and the conductance of the persistent sodium current in...
