Heat Transfer from airflow to concrete

Hi there,
I'm a relative novice to using Fluent and I wondered if somebody could give me some advice about a problem that I'm modelling. I have a 2d setup with a channel of airflow beneath a block of concrete. Above the block of concrete is a second channel of air to represent a service floor, although there is currently no airflow in this space. I have defined the zones as fluids and a solid in gambit and I have set the airflow in the bottom channel to 0.1m/s and temp of 307K. I was hoping to see the heat from the airflow move into the concrete and be stored, so the temperature should increase in the concreteover time. However, when I run the simulation the temperature across the whole space (including the concrete and service floor) stays at 307K and there is only variation of around 0.001K. Please could somebody advise me as to where I am going wrong? Thanks for your help. |
