    dct:description "A three-dimensional model which simulates the injection-production air flow rate in a tar sand bed was developed by the author in fulfillment of ERDA Contract (E(29-2)).  The model consisted of a non-linear partial differential equation derived from the continuity equation, Darcy's Law and the ideal gas equation of state.  A finite difference scheme based on the work developed  by Bruce et al. was incorporated in a computer code which determines both the injection-production-air flow rates and the pressure distribution in the tar sand bed.  The major drawback of the finite difference scheme is the question of stability, which imposes a severe restriction on the size of the time step required for convergence.  Such a restriction increased the computation time considerably and necessitated a major revision of the previous computer code.  Thus, the finite difference scheme was abandoned in favor of a more stable computer code based on the method of lines.  Furthermore, a two-dimensional formulation replaced the more cumbersome three-dimensional code used on the previous stages.  This was possible because the flow pattern obtained from the three-dimensional model exhibited negligible transverse flow normal to the bedding plane." ;
