CFD Modeling and Quality Forecasting for Cooling and Storage of Pelagic Species
In the project, a computerized thermal and hydrological model of storage tanks for pelagic catches is built. The input of the model is time-dependent ambient temperature, which in turn returns the temperature distribution of the mixture of pelagic catches and seawater stored in the tanks. That model is such an intertwined quality forecast model that indicates the development of damaging substances such as TMA and NH3 based on the temperature history obtained from the thermodynamics model. The main result of the project is the development and application of technology that makes it possible to predict the damage processes of pelagic catches at a given environmental temperature history. This technology could prove to be extremely useful in the handling and processing of pelagic catches. Collaborating companies in the project are Síldarvinnslan, Skinney‐ Þinganes and HB Grandi.
In this project a thermodynamic model of storage tanks used for cooling and storage of pelagic species is constructed. The input for the model is transient ambient temperature, which gives the temperature and velocity distribution in the mixture of pelagic species and seawater. This model is then coupled with a quality forecast model, which predicts the development of spoilage indicators such as TMA and NH3 from the temperature time series which are retrieved from the thermodynamic model. The main result of the project was the development and application of a technique which makes it possible to predict the spoilage of pelagic species given only ambient temperature history. This could prove immensely useful in the management and processing of pelagic species. The following companies take part in this project: Síldarvinnslan, Skinney ‐ Þinganes and HB Grandi.
