Heat transfer phenomenon in vertical support of LAr jacketed tank

Abstract

Storage of LAr with minimum heat is the primary condition of storage tank. Boiling temperature of LAr is 87K
and surrounding ambient temperature is in the range of 293K to 313K C. This is quite vast temperature gradient. LAr
storage tank is jacketed with outer tank with perlite insulation with required vacuum level In spite of insulation and
vacuum, heat transfer takes place. There is thermal short between inner tank and outer tank through inner support.
Heat inflow takes place trough this path to LAr and resulting in to vaporization of LAr. Study required in this area to
understand the heat transfer phenomenon in LAr tank. Heat balance analysis gives the critical value of length of
conductive path
