Abstract:
An integral method based on moment techniques and especially useful for compressible laminar flows is presented. The describing partial differential equations are first transformed to the Levy-Lees variables and then converted to integral conditions with eta to the mth power as a weighing factor. A technique for handling the variation in transport properties which explicitly arises for m0 is described. The resultant equations are applied for m0,1 with the commonly employed fourth and fifth degree polynomial profiles for velocity and stagnation enthalpy. The distinct classification of similar and nonsimilar flows within the same analytic framework is emphasized. The analysis is applied to a variety of flows for which more accurate results are available and is found to yield satisfactory results in most cases. Therefore, the present method is considered to improve somewhat the conventional integral method m0 without excessive labor. Author
