โœฆ Synopsis

In a classical endoreversible Carnot refrigeration model, irreversibility in the form of heat resistances between the reversible Camot cycle and its heat reservoirs is taken into account. This paper presents a new steady-state flow model that incorporates several internal irreversibilities, such as heat leak, friction, turbulance, etc. These added irreversibilities are characterized by a constant parameter and a constant coefficient. An optimization analysis of the model has been carried out that allows assessments of the effects of the various irreversibilities on the performance of the cycle. Numerical examples are given to illustrate the practicality of the model. Published by Elsevier Science Ltd.

## Abstract Redundancy or standby is a technique that has been widely applied to improving system reliability and availability in system design. In this paper, a general method for modelling standby system is proposed and system performance measures are derived. It is shown that the proposed genera
