(OP)
I need some information regarding this subject for my diploma.Can anybody help me?
Thank you

RE: Spray quenching.Cooling capacity of water-air mixtures.Applications

Hi Roxana,
I'm presently trying to simulate a quench cracking problem of steel. Since I know little on the subject, below are some sites I came across that gave me some lead. Some of the terminology may help during searches: Unfortunately, I dont think theres a specific reference to water air mixtures/applications but they may lead on to something.

http://www.tenaxol.com/quenchcracking/quench5.htm

This is a quoate from an abstract I fond on the web about Gerard Ludtka, a metallurgist in ORNL's Metals and Ceramics Division
"Ludtka's Quench Simulator code predicts the cooling rate that will produce a heat-treated component with the best possible features. Use of this code eliminates the need for trial-and-error experiments in part design, resulting in significant savings."

This is a project description at Purdue Univ that I found on the web:
"Material and Heat Transfer Characteristics Associated with the Spray Quenching of Aluminum Alloys
(Boiling & 2-Phase Flow lab, Purdue University)"

Another abstract I found using 'ask jeeves'
CT-65: Intensive Quenching Technology for Steel Parts. The objective of this project is to significantly improve the current methods of steel hardening relative to quality of the finished product and the overall cost of heat treatment. Quenching refers to the process of rapidly cooling metal parts from austenitizing of solution treating temperature.

Heres a paper I found on the web:
Dynamic Quenching Tests of Steels and their Evaluation by Inverse Task
J. Horský & M. Raudenský
Technical University of Brno, Technická 2, 616 69 Brno, Czech Republic E-mail: raud@kinf.fme.vutbr.cz

If your doing any FE simulations I would be interested in sharing ideas. I use a ABAQUS to conduct a sequentially coupled simulation (1st heat transfer followed by thermal stress analysis) I'm quite new to this so please excuse any lack of substance in the above.
