Abstract
This paper presents one of the first attempts to numerically model the temperature and flow distribution in ballast water heated through a continuous flow focused microwave system. The model was developed by coupling the High Frequency Electromagnetic and FLOTRAN CFD modules in the finite element analysis software ANSYS MultiphysicsTM. Temperature and electromagnetic power density for water at two salinity levels (0 and 1.5%) flowing at 1.6 l/m at an incident power level of 4.5 kW were studied numerically. Results showed that the electric field and power density distributions followed a Bessel-type function in the radial direction (maximum power density near the center of the applicator tube and minimum near the wall). Consequently, the highest temperatures were determined to be also near the center of the processing tube at both salinities. The higher temperature increase was achieved for the 1.5% salinity water. The temperature distribution obtained from the model was compared to experimental values (at several locations along the longitudinal axis) and it was found to be in good agreement, with an average error of 3.9°C for the 0% salinity study and 3°C for the 1.5% salinity study.
