Gas Foam Metry. III

First Sym etition : metry

Symmetry is a pervasive phenomenon presenting itself in all forms and scales in natural and manmade environments and its detection plays an essential role at all levels of human as well as machine perception. The recent resurging interest in computational symmetry for computer vision and computer graphics applications has motivated us to conduct an US NSF funded symmetry detection algorithm com...

Behavior of Generated Gas in Lost Foam Casting

In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...

An Experimental and Theoretical Analysis of Foam Formation in the Sour Gas Sweetening Process

Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment and might result in a situation in which the process specification...
