The melted palmoil packed into a ISO tank container at Southeast Asia get freezing during 6400 km long distance transportation to Japan, and it must make the need to melt by heating in place to use. It is important to estimate the time required for melting as accurately as possible to design the process for fuel palm oil. In this paper, the computer simulation is performed on which the solidified palm oil filled in 24kL ISO tank covered by 50mm thick rockwool as the thermal insulationis melted by flowing-in hot palm oil heated upto 85℃. The melting of palm oil in a tank is different from that of water. The melting of solidified palm oil is the isothermal process of the enthalpy conduction with the liquid-solid binary phase by phase-change in the considerably thick layer on the surface of freezed solid oil. The energy conservation equation is solved using the sphere assumption by unsteady and one dimensional finite-difference method. And by simulating slow natural convection with the effective heat conduction, it can be found that the experimental time-temperature changes can be well simulated., application/pdf}, pages = {31--42}, title = {凝固したパーム油の高温液による融解のシミュレーション}, volume = {12}, year = {2019}, yomi = {キシモト, ケン and ハマノ, マサオ and イシダ, タカシ} }
