Dear All,

I am trying to find the drop in temperature for a cross country pipeline.

The data available with me include:

The pipe traverses both above and below ground

Below ground depth is 2.5 m between Centre line elevation of pipe and ground surface

FG el 3.5 m
Cl El of Pipe 1.0 m
BOP el is -0.321 m

Pipe Radius is 2.6 m (ID)

The ambient temperature of air surroundings maximum is 40 C

The fluid inlet temperature is 35 C

Inlet mass flow rate is 8393.06 Kg/s

Above ground ambient temperature is 40 C


Can someone tell me whether the Boundary conditions I have used are fine or not.

I am a newbie with CFD.

Can someone help me with the BC for wall, and how to calculate the heat transfer coefficient value .. or should we specify the constant wall temperature
