Can someone please explain to me what the reference values "area" and "length " is for ? thanks

These reference values are not used during calculation, but only for some post-processing tasks. E.g. calculating a drag-coefficient, requires a reference area. Or if you ask Fluent to report on surface heat transfer coefficients, he uses the reference-temperature.

hope this is enough,

cheers, Laika, still orbiting

hi wat lika mentioned is correct if you are interested flow past problems and calculating coefficients like LIFT AND DRAG skin friction...... you should worry about reference area i think for 3D you can get it from projected area option bye

hi sir

i wana calculate surface nuselt number in expansion value can u explain to me what should i used for refrence value

temprature
velocity
area
height
lenghth
....
,,,,



thank u

Here a tutorial about Reference Values in 2D.
