Abstract
A pocket computer (Casio model FX-702P) has been utilized to solve some problems arising in gas dynamics. The programs reported cover algebraic calculations, solution of transcendental equations and finite difference solutions of coupled, nonlinear ordinary differential equations. In gas dynamics terms, the algebraic computations pertain to properties variation in isentropic flow, Rayleigh flow and Fanno flow. The transcendental equations solved are those arising in Prandtl-Meyer flow and oblique shock analysis. Problems of pipe flow with simultaneous friction and heat transfer, unsteady discharge of a variable-volume tank through a convergent nozzle, Taylor-Maccoll flow over a cone and flow in a rocket nozzle with secondary injection of oxidant in the divergent section, are used as illustrative examples of coupled, nonlinear ordinary differential equations.
