The natural convection boundary layer flow modeled by a system of nonlinear differential equations is considered. By means of similarity transformation, the non-linear partial differential equations are reduced to a system of two coupled ordinary differential equations. The series solutions of coupled system of equations are constructed for velocity and temperature using homotopy analysis method (HAM). Convergence of the obtained series solution is discussed. Finally some figures are illustrated to show the accuracy of the applied method and assessment of various prandtl numbers on the temperature and the velocity is undertaken.
The microwave rocket is a candidate for use as a future low cost launch system. Plasma Hollister Toronto Sale
generated by a millimeter-wave beam drives a detonation wave in a thruster tube, and the vehicle acquires impulsive thrust by exhausting the gas, similarly to a pulse detonation engine. The air breathing rate is important for thrust performance in multi-pulse propulsion. Therefore, an air-breathing mechanism using reed valves is under development. In this study, the air flow rate through the reed valves was computed and its performance was evaluated in terms of the partial filling rate: PFR. Results show that, when using reed valves, a 10–15-fold increase in Magasin Hollister Montreal thrust is obtainable over conventional performance.
