Analysis of floating-head heat exchanger bolts failure
(Timisoara, Romania, 2011)
As-received floating-head heat exchanger bolts were broken (BB) and deposite-coated. The aim was to estimate
a cause of their failure. The new bolts of the same material were used as a reference material (reference bolt ...
DETERMINATION OF THERMAL CONDUCTIVITY OF THE INSULATION MATERIALS USING NUMERICAL CALCULATION OF THE PRESSURE INCREASE
(Materials Research Society of Serbia, Crna Gora, 2011)
In the paper is presented the possibility of determination thermal conductivity for the
insulation materials, which are used in the tanks for liquid carbon dioxide, in situ. For this
purpose, was developed the mathematical ...
