We are going to konstrukt nozzels for drying.
We blows hot air to a wall,
How can a get the heat transfer coeffecient right ?
It seems that Solidworkt calculate the heat transfer coefficient from wall to air and not the opposit.
Some data are:
Tplate=24.6 degrees (konstant ?)
Plate dim. 300x106x2mm
The test nozzel is 53mm with, 300mm length and the slot is 2mm
My result in solidworks get the heat transfer coefficient about 100 [W/m^2/K]
Teoretic: coefficient about 300 [W/m^2/K]
And in labb coefficient about 300 [W/m^2/K]
Hope you can help me .
