CFD modeling of the flow field in a novel heat engine
As efficient usage of resources becomes more and more important because of their finiteness, one way to efficiently use energy is micro combined heat and power generation (mCHP). Therefore, Stirling engines excited interest for the domestic use of mCHP in recent years. Despite the promise of high efficiency due to the underlying Stirling cycle, these engines often have reliability problems because of their numerous moving parts.
The novel heat engine under investigation makes use of a thermodynamic cycle similar to Stirling, but with less moving parts, therefore having a much higher reliability. Thus, we focus on the optimization of the novel engine generator for application within a micro-CHP appliance.
