Abstract
Steam jet condensation is an efficient heat dissipation method in a two-phase phenomenon. The application of steam jet condensation spans many fields, such as nuclear power plants and chemical industries. In both normal operations and accident scenarios, direct contact condensation is an essential phenomenon in the lifetime of the nuclear power plant. Since direct contact condensation is mostly associated with drastic changes in thermal hydraulic parameters, it is prudent to predict transient parameters with a high level of accuracy to avert the possibility of an accident scenario. Fundamentally, the condensation rate, associated with heat and mass transfer, is based on the steam shape and length. Hence, this work aimed to apply a visualization technique to determine the steam shape in a DCC. To achieve this objective, a computer visualization technique using a Python algorithm was applied to evaluate the steam plume shape during a DCC. The input data for the computer visualization technique was from the output data of a numerical simulation of steam jet condensation. Results from the study showed strong reliability of the visualization vision technique in evaluating the steam plume shape in the subcooled water; however, the technique fairly predicted the steam plume boundary.
