Abstract
The supply of heat energy needed to reduce the viscosity of loaded oil in tankers carrying high pour point oil or very viscous oil must be estimated with accuracy. This is made difficult by variations in the heat transfer coefficient caused by differences in the configurations of tank bottoms and in the physical properties of the oil. Investigations of this problem, heat transfer through a tank bottom, are described. Theoretical formulas are derived for predicting heat flow at a tank bottom with the passage of time and are compared with experimental results from tests in which paraffin, as one kind of high pour point oil, and highly viscous lubricating oil were heated in a one-third-scale tank bottom structure.
