Differential expression of a new set of fluid dynamic equations in external aerodynamics 2019-01-1866
In former papers, a new set of fluid dynamic equations has been defined in the integral form. This set of equations accounts fluid dynamic phenomena in terms of Bejan number and the defined Bejan energy. In this paper, Navier Stokes equations have been formulated in terms of Bejan Number.
A preliminary algorithm has been defined and automatic mesh criteria have been proposed. The solution is provided for the case of a fluid flow over a flat plane and in the case of a wing.
Results have been compared against CFD and existing literature. An effective coincidence of the results has been obtained.
