 April 22, 2005, 10:30 how to simulate one deep well #1 arwang Guest   Posts: n/a I will simulate one geothermic well,which concerns heat exchange due to water and geotherm.The length of the well is 100m,the diameter is 20mm.the temperature on the surface of earth is 4 Ceisus ,13 Ceisus at bottom of well. Any body can give some advice to create the model.

Use that for the next 10 mm X 1m so u need 100 domain and u should write a script to save and read the output automatically and overnight u should get results ans this is only buoyancy driven flow.
