A numerical study of the arc-roof and the one-sided roof enclosures based on the entropy generation minimization
چکیده انگلیسی

This paper describes an enhanced finite-volume method for solving the arc-roof and the one-sided roof enclosures. Enclosures were assumed like two-dimensional cavities with the natural convection of air inside them. Various boundary conditions such as the greenhouse boundary conditions were considered. In order to estimate exergy destruction inside enclosures, the volumetric entropy generation in flow due to the heat transfer and the fluid friction was calculated using an enhanced scheme for finding the first derivative terms. In provided FORTRAN code, an explicit fourth-order Runge–Kutta integration algorithm was applied to find the steady state solutions. Next, the results were evaluated with other cited works. Also, performance of the one-sided roof enclosure was compared with the performance of the arc-roof enclosure based on their exergy destruction. Results showed that the entropy generation into the one-sided-roof type is less than the other.
