| It is relatively complex that transference regularity of underwater concrete tank system relating to many materials brings difficulty to calculate the temperature field of tank system storing high solidifying point crude oil. Based on experiment data of simulation test and variation regularity of temperature field of storage oil tank, we may obtain distribution data of temperature field anytime wanted and from that we will result temperature strain by calculating unsteady heat transferring with finite difference mathematical method, utilizing heat equilibrium theory and heat transference regularity to construct mathematical model and parameter relation, optimization and analyses them. Meanwhile the paper provides a series of well suitable curve charts of temperature of theory calculated compared with experiment measured and temperature strain charts. |
