The Simulation and Experimental Research of Electromagnetic Induction Heating for Sunken Wreck's Heavy Oil

In view of heating fuel in the process of pumping wreck's fuel oil underwater, a method of fuel oil heating based on electromagnetic induction is put forward with by wreck's oil tank outer panel. On the basis of electromagnetic induction and heat conduction, the mathematical model of heating process is established, FEM software is applied in the numerical simulation to carry out the temperature attenuation law of the heavy oil heating process. and Heavy oil heating simulation test by the tank model to carry out Temperature variation and temperature attenuation law. The model is used to verify the underwater electromagnetic heating of heavy oil, it can be seen that the experimental results match well with the numerical simulation of temperature variation of heavy oil heating. The electromagnetic heating heavy oil technology is simple and highly efficient in heating, has a good application prospect in the field of preventing oil leakage from shipwreck.
