The total temperature is:

Ttot = T + ( 0.5 * V^2 + k ) / cp

I have a question for you; What is the meaning of Heat Flux? In fact into the menù "get wall data" there is the function "HFlux" and this maybe or total heat trough the wall or only heat convection.

In the first case:

Heat Flux(trough the wall)=TIRA - TRAD -Heat convection

The second case:

Total heat(trough the wall)=TIRA - TRAD - Heat flux

Can you help me? Bye Massimo

Unless you are analyzing some very particular case, radiative heat transfer is generally of no importance, and unless you turn it on through the specific command it is not calculated. The heat flux in this case means convective plus conductive heat transfer.

bye and thanks, but what I would like to know is what is the meaning of total temperature what does it physically represent..?? I guess it might be important in high speed flows..

The total temperature is a very important physics fenomena in fact it is the temperature of a single particle during its motion. So the total temperature must consider the velocity component and the density of a fluid.

Bye and thank you for your help.

Excuse me but I have a problem with a wall data. My case is the following:

- I have an external and internal cylinder between that there is a hot fluid; so I have modelled the two cylinder with solid cells and the intermediate fluid with fluid cells. I'd like to display the wall data into external surface in particular I' d like to display the wall data in a normal section. The normal section can't displays the Area of the cells that lie at this section and the area is very important becouse the heat flux is for unit of area [w/m^2].

How can I get it? Bye

Tried plotting a graph? Try picking and/or creating vertices on the model and then use the command SENS to add and scan through the (already loaded) post data. If you just picked existing vertices then no need to use SENS. Load the data into the graph registers.
