The streamline model is a simulation technique which can be used to predict multi-fluid displacements along the streamlines generated from solutions to the diffusivity equation. Fluid flow is simulated mathematically by computing streamlines and their generated stream channel volumes numerically using superposition of Laplace flow potential solutions, a corrected Darcy frontal velocity, and first difference movement equations. The effects of differing fluid mobilities and displacement mechanisms are included in the model. Displacement mechanisms which describe 2-phase flow of oil and water and the buildup of an oil bank in injection operations are programmed in the mathematical model. The streamline simulator was designed to solve fluid-flow problems in reservoirs which have irregular boundaries, arbitrary well pattern developments, and stratification of microstrata in which cross flow is considered negligible. Image well techniques are used to mathematically bound arbitrarilyifer or existence, ahead of the hydorfluoric acid front, of a ures which might control the distribution of uraniumacterized by a thermally activated process. he effect of various parameters, temperature, pressure, and steam percent in hydrogen feed. Fifteen experimental runs have been completed using NiMo as the main component of thThe Q/sub 2//sup +/ value obtained for /sup 200/Hg is in agreement with previous work, but that for /sup 202/Hg is not. The results obtained are compared with the predictions of various nuclear models, and the mass dependence of Q/sub 2//sup +/ in the region 182 < A < 206 is examined.
