The one-dimensional flow in the nozzle shown in Figure 2 can be described by d dx d (puA) and dx (puA)u = -Adr =A dp dx where A is the cross-sectional area. The given conditions are p = 1 everywhere AA = 3 AB = 1 P1 = 28 P3 = 0 Assume that the fluid upstream of point 1 has negligible momentum. Formulate the discretization equations for u and p', and hence obtain the values of u, up, and p2. (Use the initial guess puA = 5, so that u = and UB = 5, and p2 = 25. Employ appropriate underrelaxation if necessary.) x wwwwww 2 3 B Figure 2. Grid points.
