Abstract : The Method of Characteristic (MOC) Nozzle Flowfield Solver code is a structured, Two-Dimensional (2-D) (both planar and axisymmetric), isentropic supersonic flow solver for converging-diverging nozzle problems under choked flow conditions. The code uses a marching step method based on a second-order modified Euler predictor and corrector scheme with iteration. The initial starting line is determined either by a user-input profile or by Sauers method for determining the sonic line. Initial wall options include either a user-input profile or a starting circular arc that can be followed by a second-order quadratic wall based on user inputs. The remaining downstream wall is then determined by the local characteristic and mass flow rate. A simple boundary-layer growth model is used to determine the viscous corrected shape. The software coding is written in FORTRAN 90/95. Input files are used to transfer information to the program.
