Governing Equations at the Ice-Ocean Interface
Published:
To model the ice-ocean boundary layer, we utilize the Navier-Stokes equations under the Boussinesq approximation. In the bulk, the governing equations can be written as follows:

We utilize the Navier-Stokes equations under the Boussinesq approximation. The governing equations can be written as follows:
Finding the Optimal Resolution for Ice-Ocean 2D Simulations
Published:
Here we present results from our 2D simulations, where we varied the model resolution to determine the optimal configuration. We analyze the evolution of key physical properties and compute the melt rate.
Finding the Optimal Resolution for Ice-Ocean 3D Simulations
Published:
We evaluate our melt ice-ocean problem in a three dimmensional configuration. We vary the vertical and horizontal resolution, as well as the Lewis number.
First excited mode at the Ice-Ocean Boundary: Impact of Initial Conditions and Lewis Numbers
Published:
In our previous 3D simulations with constant initial values for temperature and salinity, we observed that the first excited mode led to an unstable density profile, with heavier layers overlying lighter ones, for all Lewis numbers greater than 1. Here, we explore this instability by modifying the initial conditions for temperature and salinity, ranging from a uniform profile in the vertical direction to a stratified one. Additionally, we examine the effects of varying Lewis numbers.
