  The main purpose of this work is to obtain a mathematical model consistent
with the thermal behavior of concentrating solar cookers, such as
Jorhejpataranskua. We also want to simulate different conditions respect to the
parameters involved of several materials for its construction and efficiency.
The model is expressed in terms of a coupled nonlinear system of differential
equations which are solved using Mathematica 8. The results obtained by our
model are compared with measurements of solar cooker in field testing
operation. We obtained good results in agreement with experimental data.
Moreover, the simulation results are used by calculating cooking power and
standardized cooking power of solar cooker for different parameters.
