hydraulic analogy
hydraulic analogy[hī′drȯ·lik ə′nal·ə·jē] (fluid mechanics) The analogy between the flow of a shallow liquid and the flow of a compressible gas; various phenomena such as shock waves occur in both systems; the analogy requires neglect of vertical accelerations in the liquid, and restrictions on the ratio of specific heats for the gas. |
