Comparison of Heat Insulations for Cryogenic Tankers Using Analytical and Numerical Analysis

Miralbes, R (Universidad de Zaragoza) ; Valladares, D.

Resumen: This paper presented a methodology for the design of heat insulations used in cryogenic tankers. This insulation usually comprises a combination of vacuum and perlite or vacuum and superinsulation. Concretely, it is a methodology to obtain the temperatures, heat fluxes, and so forth. Using analytical tools has been established, which is based on the equivalence with an electric circuit, and on numerical tools using finite elements. Results obtained with both methods are then compared. In addition, the influence of the outer finish of the external part, due to the effect of the solar radiation, is analyzed too, and the equations to determine the maximum time available to transport the cryogenic liquid have been established. All these aspects are applied to a specific cryogenic commercial vehicle.
