Appendix B – Problem 9
B.9 Refer to the space-time grid shown in the previous examples. Equations B.15 and B.16 provide solutions for the head and flowrate at space-time grid point (C, t+Δt) using head and flowrate values at grid points (L, t) and (R, t). These equations were derived using the first-order approximations of compatibility equations in integral form (Eqs. B.9 and B.10) with the assumption that Q (more specifically Q2) in the integral terms of Eqs. B.9 and B.10 is a constant and a known value as in Q = QL,t = QR,t. What are the consequences of these assumptions on the accuracy of the results obtained from the first-order MOC approximations and more importantly on the numerical stability of the method?
