in 3d you can set up a mold block and set external heat transfer coeff. Standard ist Air. But what value is Air?
Does anbybody know?
I got some Infos:
not moving air : 2 W/m^2K
Room air : 5 W/m^2K
slight air movement: 10 W/m^2K ( I think this is passive convection)
stronger air movement: 20 - 40 W/m^2K (active convection)
But I still would like to know what parameter MOldflow uses for calculation when I set it to AIR.
Hope somebody knows.
regarding the Mold Block (3D) Air property:
Air uses the ambient temperature in the process controller (default is 25C).
You can change it at:
Process Settings > Advanced Options...
Process Controller : Edit...
tab Temperature Control
The Heat Transfer Coefficient, HTC, for Mold Block (3D) Air property is with the value of 10W/m2-C.
