In the present work a comprehensive study of turbocharger heat transfer phenomena is
discussed, showing their relevance compared to gas enthalpy variations through the turbomachinery.
The study provides an experimental ...
[EN] The behavior of small turbochargers is deeply affected by heat transfer phenomena. The external heat losses of these machines are studied and a simplified model that takes into account both radiation and convective ...

The exhaust energy can represent up to 40% of the fuel chemical energy in turbocharged internal
combustion engines. In order to calculate properly the available energy of the exhaust gases, a critical
parameter is the ...
