in this research, heat transfer enhancement and simultaneous effect of that on pressure drop inside condensers with twisted tape inserts are investigated. a refrigeration system is designed for attaining to maximum level of heat transfer with minimum pressure drop. the test condenser is a double pipe heat transformer with inner and outer diameter of 10.7mm and 12.7mm for internal pipe, respecti...

Between 1990 and 1992 an extensive artificial cavity installation program was conducted on the Francis Marion National Forest (FMNF) in coastal South Carolina where Hurricane Hugo had caused vast devastation. Four artificial cavity types were installed: drilled starts, drilled cavities, modified drilled cavities, and inserts. In 1998, we examined 443 of the artificial cavities (average age 8.5 ...

Finite element modeling of ballistic impact inserts containing titanium structures were presented in the article. The an additional layer made using additive manufacturing technology analyzed. was created from repetitive elements without connections (adjacent cells inseparable). Four variants printed placed between layers Twaron CT 750 aramid fabric to create inserts. In order assess resistance...
