Conformational Cooling Dynamics in Matrix-Isolated 1,3-Butanediol [PDF]

The Journal of Physical Chemistry A, 2009
The complete conformational space of monomeric 1,3-butanediol has been characterized theoretically, and 73 unique stable conformers were found at the MP2/6-311++G(d,p) level. These were classified into nine families whose members share the same heavy atom backbone configurations and differ in the hydrogen atom orientations.

Understanding conformal cooling in the diecasting of aluminum alloys

IOP Conference Series: Materials Science and Engineering, 2023
Abstract Heat transfer and stress distribution are studied using computational fluid dynamic and structural simulation for a conformal cooling die insert made of Maraging M300 steel by selective laser melting. The phase transformation of cooling water is studied to understand the cooling effects and stress concentration on die life.

Efficiency of Conformal Cooling Channels Inserts for Extrusion Dies

Procedia Manufacturing, 2020
Abstract During aluminum extrusion process, critical temperatures can be reached both in the profile and in the tooling set due to the high pre-heating temperatures and to the work spent in overcoming friction at the workpiece/tool interfaces and in deforming the billet that is converted into heat.
