Abstract The heat contained in internal combustion engine exhaust gases can be converted into mechanical energy by using an Inverted Brayton Cycle (IBC). In this paper, five different IBC versions are numerically modeled and optimized to maximize their specific work output: (i) basic IBC, (ii) IBC with liquid water drainage (IBC/D), (iii) IBC with liquid water drainage and a steam turbine (IBC/D/S), (iv) IBC with liquid water drainage and a refrigeration cycle (IBC/D/R), and (v) IBC with liquid ...

Abstract Most turbocharger gas stands are designed to map performance under steady flow conditions. However, when connected to an internal combustion engine (ICE), the turbine is exposed to pulsatile flow. In order to enable a full analysis of the unsteady flow and turbocharger performance, it is crucial to quantify unsteady flow effects in the gas stand tests. This paper presents the development and use of bespoke experimental hardware that aims to generate flows in a gas-stand with characteris...

Abstract This paper details an extensive experimental investigation of a novel throughflow micro-wave rotor with symmetrically cambered passage profiles designed for shaft power output as well as pressure exchange. This is the first time comprehensive experimental data from a power generating wave rotor is presented in a peer-reviewed journal. Moreover, the significance and renewed interest in wave rotors for a wide range of applications from refrigeration to micro-gas turbines makes this experi...
