I am simulating a flap plate HE in fluent 2D case where the bottom wall has a constant heat flux condition, now to find the heat transfer coeffecient at any x location on the wall i'll use
h = Q/(A*(T_w-T_bulk)
T_w is the wall temperature at any x location which can be determined from the plot of static temperature
T_bulk in mean bulk velocity

The problem is HOW WILL I FIND THIS T_BULK FOR A X LOCATION using fluent cause the fluid temperature at every section is constantly changing.

Also how should i work my heat flux value if i have to keep the difference between T_wall and T_bulk around 30degree.
Inlet air temperature is 300k

my thesis is stuck up because of this. Please help it's urgent
