ABSTRACT:
Analytical foundations are laid down for evaluating the performance of dish-Brayton power systems. The dish-Brayton power system analyzed here included three subsystems as part of the system: collector, receiver, and engine. This groundwork includes various assumptions and approximations
Based on the above analytical foundations, models are developed for collector, receiver, and engine subsystems. These models are integrated via a computer code to obtain a system model of the dish-Brayton power module. The design variables and operating variables of the various components are used as input to the model. The model evaluates system efficiency in terms of subsystem characteristics and determines optimum system efficiency for each set of subsystem characteristics.
The computer model is structured such that the various operating conditions and the component variables are input to the code. This flexibility of the computer code is well suited for performing a sensitivity analysis which will show the effect of input variables on system efficiency. Such an analysis is expected to indicate those areas of the power system which have greatest potential for system efficiency improvement.

Such a system model, apart from being able to evaluate the performance of the system, can be used in analyzing the system to delineate the effect of possible advanced technology improvements on overall system performance.Based on the above analytical foundations, models are developed for collector, receiver, and engine subsystems.
