ArtificialGroundFreezing_convect

This example is to simulate artificial ground freezing. To simplify the model only one freeze pipe is installed. The following features are illustrated in this example.-- Frozen ground developed in ground freezing process, -- Water flow around frozen ground, and -- Thermal convection effect on temperature distribution and finally effect on frozen ground regime.

CanalBankFreezingThawing_50h

This is a shorter version of the CanalBankFreezingThawing model presented in the Example Manual. Example is to illustrate hydrothermal coupling in the simulation of soil and ice freeze-thaw behavior on a canal bank. The water in the canal is also included in the analysis. The model simulation time is 50 hours, The canal bank is freezing in the first 25 hours, and after that time, the thawing process happens.

ConvectiveBoxHeatedBelow

A simple box model is used to illustrate the convective airflow when a warm temperature (TH) is introduced to the bottom of the box and a cooling temperature (TL) is applied to the top. This example uses a SVAirFlow and SVHeat coupled model to simulate natural convection of air or thermo-buoyant motion under the different temperatures TH and TL.
