Iceberg simulation





    Ones tried, at first, to simulate the formation of an iceberg.
Indeed, the iceberg seems to be the easiest case to begin learning diphasic mode under Fluent.
 
 

I. Parameters

 1. The mesh


    So, to do this, ones has created a simple mesh made under PREBFC.
This mesh is a 2D structured one because ones did not need unstructured mesh for such a simulation.
Ones defined symmetries on each lateral sides and walls upstairs and downstairs.


 
 

 2. The material


    At first, we had to activate the two phases mode of Fluent (The method is explain before in Fluent manual), gravity option was activated too. The three new properties of the material has been added to the properties panel as shown after:  Melting heat, Solidus temperature, Liquidus temperature. The material chosen is liquid water which is become solid-liquid material.

 3. The limit conditions


    Ones had to define two different limit conditions on each wall to simulate the ice and the water.
Indeed, downstairs, the temperature was fixed to 275 K to impose liquid water and upstairs, the temperature was fixed to 263 K to impose ice.
 
 

 4.  The initial conditions


    Ones initialized the interior of the domain with a temperature of 272 K which means ice everywhere.
In fact, as the simulation has been done with steady option,  whatever temperature you put for initial condition, the same results you got.
