Changing aggregate state

      Hi, can anyone recommend me a tutorial in which the heat transfer is shown, 
      and the fluid from which the heat is transferred grows from the aggregate state (liquid to gaseous)?

      Hi,

      You will have to use Multiphase flow model to capture the phase change from liquid to gas. You can follow the below tutorials to learn how to set up multiphase flow. To include heat transfer effects, you will have to enable energy equation under models and have to specify thermal boundary condition and material properties. 

      Chapter 20: Using the VOF Model (ansys.com)

      Chapter 22: Using the Eulerian Multiphase Model (ansys.com)

      To understand how to set up heat transfer condition, you can refer toChapter 24: Using the Eulerian Granular Multiphase Model with Heat Transfer (ansys.com). However, please note,this specific tutorial is to model granular flow.
