The calculation of flows in the three-dimensional nozzles based on the approximate factorization method
In the given work the method of calculation for equili-brum sub-transsonic flows is offered and the results of its application are given. It is based on the method of approached factorization for the solution of the complete speed potential equation, which has been written down in the conservative form on orthogonal grid, connected with a contour of a nozzle. This method allows calculating flows in nozzles, having the complex form of combustion chamber, particularly the flush-mounted nozzle. The method gives the best correlation with the experiment in comparison with a usual approached factorization method. Such results are explained by using of an orthogonal grid, which improves the approximation of the initial differential equation.
