Bachelor Thesis: Development of Model Ice Growth Prediction Model

Bachelor Thesis in Physical Oceanography at the Universität Hamburg 2021

Abstract:

I have developed a prediction model for the growth of aqueous ice in the Hamburg Ship Model Basin. The prediction
is based on a basic thermodynamic ice growth model. I determined the tank specific parameters with an estimation
algorithm from measured data. I tested the theoretical accuracy of the parameter estimation as a function of data size
with virtually generated data. The prediction model describes ice growth with a standard deviation of 2.2 mm. I propose
a measurement plan that is likely to improve the model. I investigated the influence of water temperature on ice growth
with a separate model. Contrary to empirical experience, I found the impact of the water temperature on ice growth to be
negligible in the context of the temperature variation in the ice tank.
