How to simulate heat transfer and water flow
 

Hi.I have one U pipe pluged into soil which exchanges the heat between the water in pipe and soil surrounding it.the wall thickness of pipe is 20mm.the inner semi-diameter is 10mm.the soil thickness is 3000mm.The deepth of all is 3000mm.Now I want to simulate them.How can I do? especially the contact of two material.wish you help.

basics for simulations of airflow..
 

hi

i would like to start a project on simulation of air flow thru the heatexchanger using fluent.so i would like 2 know the basic contents for my project. kindly post ur valuable suggestions 2 me.
