Liquidius and solidius temperatutrure

Saima · April 12, 2009, 20:32

Hi ,

I have a problem in which a heater is on leading edge of an airfoil and this airfoil is placed in Icing wind tunnel. Air is inside the tunnel at -5C. And water spray by using atomizer is also there.

I have to figure out what will be the temperature of airfoil at different places.

Could you tell me which model should i use? Currently i am using (solidification+VOF).

I want to know what is the liquidus and solidius temp in this situation?

It is very urgent.

Many Many thanks in advance.
Regards,
Saima

liquidus (melting) and solidus(solidification) is the term used for alloys which represents the start and end of mushy zone. water i guess should be modeled as pure susbstance so the melting and the solidification temperature should be same. Please read some standard thermodynamics textbook

So u mean its 273k or 0C for both.

Thank u so much i was also thinking that but i was not sure.
Thanks alot.
