Oil tankers carrying high-viscous oil have to equip with the oil heating system taking account of characteristics of viscosity on temperature. In general, the viscosity of high-viscous crude oil changes rapidly according to a thermal change near a normal temperature. In order to investigate the natural convection and the thermal state in oil tank, the numerical analysis on velocity and temperature during heating up is carried out by the finite element method. By the results of analysis, the relations between the distribution of oil temperature in tank and the arrangement of heating coil or the supplied heat quantity are clarified., 長崎大学工学部研究報告, 14(23), pp.149-156; 1984}, pages = {149--156}, title = {高粘度油の加熱による自然対流と温度分布について}, volume = {14}, year = {1984} }
