A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. Attempts to create such a model established the more general field of celestial results of this simulation can be compared with past measurements to check for accuracy and then be used to predict.
The model was validated against experimental data as well as a data set which was obtained by an accurate numerical model describing the thermal performance of. of the NASA Lewis Research Center's Solar Dynamic Ground Test Demonstration (GTD) project. In the present paper, a physical and numerical model is developed to study the cyclic behavior of the solar heat receiver component of the aforementioned GTD system.

Abstract. Solar-distillation systems have many applications. Various parameters, i.e., inclination angle of the transparent-glass cover, orientation of the distillation unit, wind velocity, sky and ambient temperature, basin-water depth, scaling of basin liner, and bottom insulation, significantly influence the productivity of solar-distillation : G.
Tiwari, Lovedeep Sahota. In this paper, the main focus is set on the utilization of parametric methods for the quantification of causative relationships in static and dynamic deformation processes. Parametric methods are still ‘exotic’ in engineering geodesy but state of the art e.g.
