| Description: | Technical Report Summary: The design, construction, and operation of the hydraulic analog computer developed by the Corps of Engineers in order to improve techniques for predicting subsurface temperatures, especially frost and thaw penetration below airfield pavements, are described. The computer and the analogous relationships among parameters in the thermal and fluid-flow systems are discussed, and the developments in hydraulic analogs in various countries are outlined. The design requirements, including the simulation of freezing and thawing, the selection of the working fluid, and the assembly of the various components of the computer are described. The programming procedures for the computer are outlined, and the solution for a sample problem is given. The computer has been found very useful in solving complex one-dimensional freezing and thawing problems in soil, and its applicability for solving other diffusion problems in engineering is broad. |
