Abstract:

Stability analysis of miscible displacement has several applications in industries such as oil recovering and ground water tables. In this article an analytical solution based on Tan and Homsy’s results for stability analysis in t = 0 has been presented. Moreover a novel semi analytical solution based on weighted residual method has been used to solve the Fourier space equations. The results have been shown as σ (disturbance growth rate) - k (wave number) profiles for different values of mobility ratios and times. A comparison between this work and the results of the other researches has been presented.
