Theoretical evaluation of heat transfer in dry cargo ship's tanks using thermal oil as a heat transfer medium. (Theoretische evaluatie van de warmteoverdracht in de tanks van droge-ladingschepen bij toepassing van thermische olie als warmtetransportmedium)
report
Heat transfer by means of suitable organic fluids has been applied succesfully in industry. The advantages of these fluids with respect to steam for shipboard application are a.o.: low vapourpressure at relatively
high temperatures and no corrosion or erosion of metallic surfaces. Disadvantages are the relatively low specific heat capacíty, the cost price and the inflammability of most of these fluids. Since the physical properties of organic fluids, that determine the heat transfer capacity, vary substantially from those of steam, it is necessary to verify the design calculations of the heating system. In this report a theoretical method is developed for the evaluation of the heating surfaces to be installed in double bottom- and deeptanks of a dry cargo motorship. It is understood that the method should be suitable for designers, who are not familiar with heat transfer calculations. To illustrate the procedure the method is applied to the
heating systems of two sisterships under construction for the Royal Netherlands Steamship Company.
