Abstract

The concentrated solar systems by using Stirling
engines become more and more important as its renewable, cheap operational and
management aspects. Thus, the usage of power sources related to SEs and their
model and simulations are growing among the scientists for better efficiency
and performance under different operating states. In the present study, a new
SE simulation scheme has been developed by operating under Matlab/Simulink. The
code mainly models and studies the thermos-mechanical performance of a beta
type SE. The model includes the extensions from the solar power side under a
constant temperature together with thermal and mechanical outputs. Since it has
been a nonlinear model, some transient and dynamic phenomena have been taken
into account to complete the system operation from start-up to full power
state. The detailed model and simulation results are promising by comparing the
earlier analyses even for using a semi-empirical formulation for the
electricity conversion.
