how to simulate one deep well
 

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.

certainly you do have to consider a 2D case, the density has to be a function of temperature. The rest should be easy.

thanks.but I find it produce too many mesh face elements.I use axissymmetic 2d model.so the semi-diameter is 10mm with the deepth 100m.If the interval size is 2 then it will create 5*50000 face elements.How to simulate easily.

solve for a part of a domain eg.: 10 mm X 1m. 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.
