Direction of wind for forced convection

Click For Summary
SUMMARY

The discussion centers on the application of convective heat transfer coefficients in forced convection scenarios. Specifically, when air flows at a velocity of 5 m/s, the convective coefficient is established at 30. The key question is whether this coefficient applies uniformly across all faces of the channel or solely to the face directly exposed to the airflow. The consensus indicates that the convective coefficient should primarily be applied to the face where the wind originates, rather than uniformly across the entire channel.

I am wondering if in a case where the air velocity comes from one face as shown in the picture. Can I assume the whole area going along the channel will be subject to the same convective coefficient?

Thanks

So I'm not sure if it was clear...
If the convective coefficient for 5m/s is 30. Do I use that for all faces of the channel, or just the front? (where the wind is coming from?
