Sažetak
This paper proposes and analyzes a novel heating coil design for cargo oil tanks, characterized by a series of heating coil bundles asymmetrically extended along the middle part of the tank. Each heating coil bundle is a single heating body comprising several horizontal heating tubes, stacked vertically. During heating, each bundle generates a large-scale circulation that cross-flows through the empty spaces between the tubes ; thus upgrading a heat transfer mechanism from less effective natural convection to more effective mixed convection. The proposed heating coil design is numerically analyzed with OpenFOAM software using a finite volume method. Simulated results indicate that for fuel oil with 585 mm2/s viscosity heated by 50A-size steel coils driven by 8 bar steam, a 66, 9% increase in the heat transfer coefficient may be achieved.
