We consider the charged d-dimensional black holes in a cavity extended phase space and investigate heat engine Joule-Thomson (JT) expansion. Since structure of is similar to anti-de-sitter (AdS) cases, we take as working substance calculate their efficiency Carnot cycle rectangular cycle. Also, discuss whether JT expansion consistent with AdS cases conclude effect different boundary conditions ...

The expansion of molten aluminum foam was studied to determine flow mechanisms in the cellular melt. The structure of the foaming melt evolved through a series of deformation stages before the foam stabilized and solidified. Changes in cell geometry during foam expansion were observed at different positions within the mold cavity and analyzed to determine flow mechanisms. The deformation patter...
