PL Autorzy niniejszego artykułu przedstawili nową ideę obiegu termodynamicznego realizującego izotermiczne rozprężanie w turbinach gazowych. Możliwa jest realizacja przemiany izotermicznego rozprężania gazu, pod warunkiem, że praca wykonana przez gaz będzie równa energii dostarczanej z paliwem w trakci[...]
EN Authors of the present paper propose a new gas turbine cycle which includes an isothermal process implemented by internal combustion turbine. It is possible to achieve an isothermal expansion of gases if heat released during the combustion of gas is equal to the mechanical work of expansion. The que[...]
