This paper presents a numerical investigation of the heat transfer inside a micro gas turbine
and its impact on the performance. The large temperature difference between turbine and
compressor in combination with the small dimensions results in a high heat transfer causing
a drop in efficiency of both components. Present study aims to quantify this heat transfer and
to reveal the different mechanisms that contribute to it. A conjugate heat transfer solver has
been developed for this purpose. It combines a three-dimensional (3D) conduction …
